As someone else mentioned, you can read the book of Romans or the epistle of James to find out by yourself why this idea is absurd.
But simplified, say you have a spouse who you dearly love. And say you found out that said spouse would forgive and get over any nasty thing you did to them.
Would that mean that you'd start being evil to them just because you can?
Or would that be yet another reason to try to live up to what such a spouse deserves?
edit:
Actually, I think I misunderstood your issue with what I said.
To clarify, a Christian will strive to do good and be better, but knowing that we'd never be able to be good enough, and that we can only be/do good through Christ, so we never deserve or earn our salvation (hence Grace), but we put our hope in Christ (hence Faith).
