After discussing with the Corinthians the notion that one who is a Christian cannot be in communion with sin or sinners anymore than righteousness can have fellowship with lawlessness, or light with darkness, or Christ with Satan, or the temple of God with the temple of idols, Paul strongly encourages the Christians there to Come out from among them and be separate, says the Lord. Do not touch what is unclean, and I will receive you (2 Corinthians 6:17). Not only does Paul use the filthiness or the defilement that comes from sin as a motivation, he shows them the promises of God that accompany such a detachment from sin: "As God has said: 'I will dwell in them And walk among them. I will be their God, And they shall be My people'" (2 Corinthians 6:16). And then, "I will be a Father to you, And you shall be My sons and daughters, Says the LORD Almighty" (2 Corinthians 6:18). What wonderful promises and what amazing motivation to separate ourselves from the defilement of sin! In context, the "unbelievers" from which he commands the Corinthians to be separate are the false teachers who had come in among them. He calls false teachers "unbelievers", even though they believed in Jesus.
