That part of my salvation has been done for me. I had no say in the love God has shown for me. I do have a say in whether I obey His word.
I don't know if we have got stuck on samantics here or what. So, let me ask...Do I go to heaven no matter what I might or might not do?
No, ALL of your salvation has been done for you. IT IS FINISHED. You can add nothing to His perfect work. What you add would be tainted by sin. All you can "do" is respond in thankfulness. As a child of God, the "new man" in you does not _want_ to sin. But the "old man" will struggle against that. In faith, you do not want to sin. So why do you ask whether what you do matters? How does your Friend Jesus want you to act? Does He want you to blaspheme, curse, steal and kill? No, and as His friend, you don't want to. So why ask how much you can sin and still be saved?
