(For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ:
Many walk. Follow not evildoers, because they are "many" (Exodus 23:2). Their numbers are rather a presumption against their being Christ's "little flock" (Luke 12:32).
Often. There is need of constant warning. The Lord and His apostles speak more against empty professors (as the Pharisees) than against open scoffers.
Weeping (Romans 9:2). A hard tone in speaking of the inconsistencies of professors is the opposite of Paul's spirit and Jeremiah's (Jeremiah 13:17: cf. Psalms 119:136).
Enemies of the cross of Christ - in practice, not in doctrine: practically denying 'that they who are Christ's have crucified the flesh' (Galatians 5:24; Galatians 6:14; Hebrews 6:6; Hebrews 10:29).
