True love for our brothers and sisters in Christ will sometimes require confrontation. In addressing certain patterns of sinful behavior evident among the Corinthian church, the apostle Paul decided to make a “painful visit” to Corinth in order show tough love and speak hard truth that might wake up the Corinthians to an understanding of what was wrong with their actions.
There is a particular type of faith that we can possess which is the same type of faith that we see in the nine who didn't return. It is a faith that is commonly birthed from experiencing circumstances of great desperation. It's a faith that cries out to God for mercy and is even willing to try anything the Lord might prescribe. However, it's a faith that at its core is seeking personal gain rather than God’s loving grace. It's a faith that cares more about what God has to offer rather than the offer of God Himself.
