Jud 1:4 (KJV) For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.

How does “all things are lawful but not expedient” turn into a lust to sin?
