All relationships require some level of separation. Marriage requires "forsaking all others," citizenship requires "renouncing all other allegiances, and to be a child of God requires forsaking all other masters. Romans 10:9 declares that salvation comes from believing God raised Jesus from the dead and confessing Jesus as Lord. If Jesus is Lord of your life, you have forsaken all other lords and renounced all allegiance and fidelity to any other lord.

2 Corinthians 6:14-7:1 is not a passage that is hard to understand, but it is one that offends the one who seeks to be friends with Christ and the world. It has two commands. One is a prohibition, and the other is a response to the transformation of the gospel. Both commands call the saints of God to live according to the righteousness of God and put away all defilements of the world.
