Christians ought not to be yoked up with non-Christians. God's people ought to separate from the Devil's people. Twice-born people are entirely different from once-born people and so should keep themselves separate. Certainly we Christians should love lost people, should be good neighbors with them and should seek to win them to Jesus, but when it comes to sweet, close fellowship, we need to rake a close look at II Corinthians 6:14-18, as Dr. Rice shows us in this pamphlet.
