At that time Joshua summoned the Reubenites and the Gadites and the half-tribe of Manasseh, and said to them, “You have kept all that Moses the servant of the LORD commanded you and have obeyed my voice in all that I have commanded you. You have not forsaken your brothers these many days, down to this day, but have been careful to keep the charge of the LORD your God. And now the LORD your God has given rest to your brothers, as he promised them. Therefore turn and go to your tents in the land where your possession lies, which Moses the servant of the LORD gave you on the other side of the Jordan. Only be very careful to observe the commandment and the law that Moses the servant of the LORD commanded you, to love the LORD your God, and to walk in all his ways and to keep his commandments and to cling to him and to serve him with all your heart and with all your soul.” So Joshua blessed them and sent them away, and they went to their tents.
Now to the one half of the tribe of Manasseh Moses had given a possession in Bashan, but to the other half Joshua had given a possession beside their brothers in the land west of the Jordan. And when Joshua sent them away to their homes and blessed them, he said to them, “Go back to your tents with much wealth and with very much livestock, with silver, gold, bronze, and iron, and with much clothing. Divide the spoil of your enemies with your brothers.” So the people of Reuben and the people of Gad and the half-tribe of Manasseh returned home, parting from the people of Israel at Shiloh, which is in the land of Canaan, to go to the land of Gilead, their own land of which they had possessed themselves by command of the LORD through Moses.
And when they came to the region of the Jordan that is in the land of Canaan, the people of Reuben and the people of Gad and the half-tribe of Manasseh built there an altar by the Jordan, an altar of imposing size. And the people of Israel heard it said, “Behold, the people of Reuben and the people of Gad and the half-tribe of Manasseh have built the altar at the frontier of the land of Canaan, in the region about the Jordan, on the side that belongs to the people of Israel.” And when the people of Israel heard of it, the whole assembly of the people of Israel gathered at Shiloh to make war against them.
Then the people of Israel sent to the people of Reuben and the people of Gad and the half-tribe of Manasseh, in the land of Gilead, Phinehas the son of Eleazar the priest, and with him ten chiefs, one from each of the tribal families of Israel, every one of them the head of a family among the clans of Israel. And they came to the people of Reuben, the people of Gad, and the half-tribe of Manasseh, in the land of Gilead, and they said to them, “Thus says the whole congregation of the LORD, ‘What is this breach of faith that you have committed against the God of Israel in turning away this day from following the LORD by building yourselves an altar this day in rebellion against the LORD? Have we not had enough of the sin at Peor from which even yet we have not cleansed ourselves, and for which there came a plague upon the congregation of the LORD, that you too must turn away this day from following the LORD? And if you too rebel against the LORD today then tomorrow he will be angry with the whole congregation of Israel. But now, if the land of your possession is unclean, pass over into the LORD's land where the LORD's tabernacle stands, and take for yourselves a possession among us. Only do not rebel against the LORD or make us as rebels by building for yourselves an altar other than the altar of the LORD our God. Did not Achan the son of Zerah break faith in the matter of the devoted things, and wrath fell upon all the congregation of Israel? And he did not perish alone for his iniquity.’”
Then the people of Reuben, the people of Gad, and the half-tribe of Manasseh said in answer to the heads of the families of Israel, “The Mighty One, God, the LORD! The Mighty One, God, the LORD! He knows; and let Israel itself know! If it was in rebellion or in breach of faith against the LORD, do not spare us today for building an altar to turn away from following the LORD. Or if we did so to offer burnt offerings or grain offerings or peace offerings on it, may the LORD himself take vengeance. No, but we did it from fear that in time to come your children might say to our children, ‘What have you to do with the LORD, the God of Israel? For the LORD has made the Jordan a boundary between us and you, you people of Reuben and people of Gad. You have no portion in the LORD.’ So your children might make our children cease to worship the LORD. Therefore we said, ‘Let us now build an altar, not for burnt offering, nor for sacrifice, but to be a witness between us and you, and between our generations after us, that we do perform the service of the LORD in his presence with our burnt offerings and sacrifices and peace offerings, so your children will not say to our children in time to come, “You have no portion in the LORD.”’ And we thought, ‘If this should be said to us or to our descendants in time to come, we should say, “Behold, the copy of the altar of the LORD, which our fathers made, not for burnt offerings, nor for sacrifice, but to be a witness between us and you.”’ Far be it from us that we should rebel against the LORD and turn away this day from following the LORD by building an altar for burnt offering, grain offering, or sacrifice, other than the altar of the LORD our God that stands before his tabernacle!”
When Phinehas the priest and the chiefs of the congregation, the heads of the families of Israel who were with him, heard the words that the people of Reuben and the people of Gad and the people of Manasseh spoke, it was good in their eyes. And Phinehas the son of Eleazar the priest said to the people of Reuben and the people of Gad and the people of Manasseh, “Today we know that the LORD is in our midst, because you have not committed this breach of faith against the LORD. Now you have delivered the people of Israel from the hand of the LORD.”
Then Phinehas the son of Eleazar the priest, and the chiefs, returned from the people of Reuben and the people of Gad in the land of Gilead to the land of Canaan, to the people of Israel, and brought back word to them. And the report was good in the eyes of the people of Israel. And the people of Israel blessed God and spoke no more of making war against them to destroy the land where the people of Reuben and the people of Gad were settled. The people of Reuben and the people of Gad called the altar Witness, “For,” they said, “it is a witness between us that the LORD is God.”
(Joshua 22 ESV)
When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.” And all were amazed and perplexed, saying to one another, “What does this mean?” But others mocking said, “They are filled with new wine.”
But Peter, standing with the eleven, lifted up his voice and addressed them: “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. For these people are not drunk, as you suppose, since it is only the third hour of the day. But this is what was uttered through the prophet Joel:
“‘And in the last days it shall be, God declares,
that I will pour out my Spirit on all flesh,
and your sons and your daughters shall prophesy,
and your young men shall see visions,
and your old men shall dream dreams;
even on my male servants and female servants
in those days I will pour out my Spirit, and they shall prophesy.
And I will show wonders in the heavens above
and signs on the earth below,
blood, and fire, and vapor of smoke;
the sun shall be turned to darkness
and the moon to blood,
before the day of the Lord comes, the great and magnificent day.
And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.’
“Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know—this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. God raised him up, loosing the pangs of death, because it was not possible for him to be held by it. For David says concerning him,
“‘I saw the Lord always before me,
for he is at my right hand that I may not be shaken;
therefore my heart was glad, and my tongue rejoiced;
my flesh also will dwell in hope.
For you will not abandon my soul to Hades,
or let your Holy One see corruption.
You have made known to me the paths of life;
you will make me full of gladness with your presence.’
“Brothers, I may say to you with confidence about the patriarch David that he both died and was buried, and his tomb is with us to this day. Being therefore a prophet, and knowing that God had sworn with an oath to him that he would set one of his descendants on his throne, he foresaw and spoke about the resurrection of the Christ, that he was not abandoned to Hades, nor did his flesh see corruption. This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing. For David did not ascend into the heavens, but he himself says,
“‘The Lord said to my Lord,
“Sit at my right hand,
until I make your enemies your footstool.”’
Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified.”
Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.” And with many other words he bore witness and continued to exhort them, saying, “Save yourselves from this crooked generation.” So those who received his word were baptized, and there were added that day about three thousand souls.
And they devoted themselves to the apostles' teaching and the fellowship, to the breaking of bread and the prayers. And awe came upon every soul, and many wonders and signs were being done through the apostles. And all who believed were together and had all things in common. And they were selling their possessions and belongings and distributing the proceeds to all, as any had need. And day by day, attending the temple together and breaking bread in their homes, they received their food with glad and generous hearts, praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved.
(Acts 2 ESV)
Something to Consider
Acts 2: What shall we do in response to hearing the gospel? Sometimes the answer given is one that is surely different than the one Peter gives here. Perhaps we've heard something like this: “Close your eyes, repeat this prayer, ask Jesus into your heart, and raise your hand if you prayed.” If this was indeed the way we were intended to respond to the gospel then there’s no doubt that it would have been made clear right here in Scripture. However, Scripture provides a different answer concerning “What shall we do?”
Peter was clear and concise, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.” That moment the gospel pierces our heart we ought to feel the wound of our depravity leading to an outflow of godly sorrow. A sword through our heart signals it’s time to surrender. It’s time to turn away from our own self-ruled kingdom, and time to turn towards the King and His Kingdom. And it’s time to repent and to identify our allegiance to our new King through the rite of baptism.
Repentance is not repeating a prayer and raising our hand. Repentance is the Spirit of God sparking a revolution in the depths of our soul. It is a radical change of our head, heart and hands. It means to completely change our mind, desires, and actions. Repentance is the only proper response to God's gospel of grace, and baptism is the proper affirmation of our new allegiance.
"Brothers, What shall we do?" There's only one answer. Repent and be baptized. Surrender and swear a new allegiance. You are no longer your own.
