Perhaps few Jesus followers actually do cross the line of mocking God. But if James 2:10 means anything, it serves as a reminder that in fact, "there is no distinction, for all have sinned and fall short of the glory of God" (Romans 3:23). We all need help once in a while.
Sometimes that help takes the form of sever intervention. Hopefully more often we intervene before drastic action is needed. But the purpose in every such intervention is to restore the sister or brother to the faith and fellowship of the redeemed. And that's the thing we must all remember: ours is a fellowship of the redeemed. We stand on level ground at the foot of the cross.
