In addition,

There are those people, maybe even whole denominations, who think a aperson has to be 'resaved' after every sin. On elady told me she had been saved 8 times in the last 15 years! I told her she sure didn't sin much! I also asked her to describe what sin was. She took a very narrow view of it. But the point is that these people are living very legalistically, as if they were under the law [maybe they are?]. But i think a proper reading of hebrews 6 would help some of them understand the fallacy of their position. Even some Arminian readings of it would stop that practice. Some Arminians read it to say that once you lose your salvation, you can't get it back.

But what Hebrews is teaching us is that Jesus paid for our sins once for all. That we are in a new covenant with God that overcomes our faithlessness, NOT that our faithlessness could cause us to be estranged from God and burnt in hell. But Hebrews also wants to stike a blow against lawlessness: that simply thinking our faithlessness doesn't keep us from heaven so lets go and sin without impunity.
