Paul reminds us to keep a close watch on others and a close guard on our faith.
One needs to trust only a few.....
Be sure the ones we trust cling to sound biblical, apostolic doctrine. Even though Pual mentioned many as his friends and acquaintances in Romans 16, few were there for him when he most needed them (2 Timothy 4:16). . . . but God!
Love God . . . Love people, but know whom/Whom you can trust!!!!
