The Unequal Yoke
The Best of C. H. Mackintosh

While there are many New Testament passages that make it clear that God assumes Christians know they should only date Christians, such as 1 Corinthians 7:39, 9:5; the clearest passage about this command of God is found in 2 Corinthians 6:14-18. In his loving yet biblical way, Mackintosh warns about Satans trap of being married to a non-Christian and points out that Gods love is always available for his own children caught in this trap.
