Living, not professing, is what matters

^15-20 “Be on your guard against false religious teachers, who come to you dressed up as sheep but are really greedy wolves. You can tell them by their fruit. Do you pick a bunch of grapes from a thorn-bush or figs from a clump of thistles? Every good tree produces good fruit, but a bad tree produces bad fruit. A good tree is incapable of producing bad fruit, and a bad tree cannot produce good fruit. The tree that fails to produce good fruit is cut down and burnt. So you may know men by their fruit.”
