Paul writing to the Colossians warns them about straying from the gospel. The letter was for the church at Colossae and Laodicea. When people become Christians, there is a pull to go back to what they had. Because walking in the unknown is scary. Paul warns the church about this. When you gave your life to Jesus, He renewed you back to the way you are supposed to be. If you go back to the sin of the past, it will destroy what God has done in you. In Colossians, Paul is showing us how to fight heresy. It is by telling the truth in love. The truth is the gospel of Jesus Christ. God loves everyone and wants them to come home.
