If we have known and then rejected the message about Christ, God will surely punish us.

Hebrews 10:26-31

26 We(inc) must do those things, because if we deliberately and habitually sin after we have known the true message about Christ, no other sacrifice will remove our guilt for having sinned in that way. 27 Instead, we must fearfully expect that God will judge and angrily punish his enemies in a furious fire [MET]. 28 Everyone who rejected the laws that God gave Moses was mercilessly killed when at least two or three people testified that they had done that. 29 That was severe punishment. But Christ is ◄God’s Son/the man who is also God►. His blood, by means of which he put into effect the new covenant, is sacred. Because of Christ’s [MTY] blood flowing for us when he died, God freed us from our guilt. So, you can be sure [RHQ] that anyone who shows contempt for those truths and who insults the Spirit of God, the one who acts with kindness toward us in a way we do not deserve, deserves to be punished even worse than those Israelis were punished [MET]! 30 We can be sure of that (OR, need to think about that carefully) since we know that God said, “I myself will get revenge on those who sinned, and I will punish them as they deserve [DOU].” Moses wrote, “The Lord will judge his people.” 31 It will be a terrible thing if God who is all-powerful [MTY] seizes and punishes you [IDM]!
