If we do not want to sin, then we don't need to be saved from sinning, we need to try our best not to sin. What good is it to know that one can sin all they want, but because they have a get out of jail free card, they will be fine in the end? That isn't salvation from sinning, its an excuse to sin, and nobody who believes in whatever will be able to fully stop sinning anyway. The only difference between a believer and an unbeliever is the belief in the content of a few sentences. They are both still sinners.
They both say "the person who sins, only he shall die." They don't follow it up with "unless they believe in such and such."
Isaiah 11v4 simply states "he shall...slay the wicked with the breath of his lips." Of course, what is meant by slay is not really laid out, so you can interpret it to mean whatever you want.
Psalm 92v7 simply states "though all evildoers blossom, it is only that they may be destroyed forever." How is this not just a suggestion that evil people will get what's coming to them, and instead a suggestion about the afterlife? Very open to interpretation, once again.
I don't care what Rev 19vs11,14,15; and Matt 25vs31 have to say, for the point of my argument, because they are in the new testament.
