Mark 6
11 And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city.
12 And they went out, and preached that men should repent.
13 And they cast out many devils, and anointed with oil many that were sick, and healed them.
Revelation 22:14
Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
Definately looks like people are expected to do something more than claim 'grace'.
Well, of course they are. I never said otherwise. "By their fruits shall ye know them."
