-Removed-I think you misunderstand a critical point; Satan doesn't win because Satan destroys billions. What Jesus is protecting us from isn't Satan; Satan is nothing compared to God; Jesus is protecting us from God, not the devil. God is HOLY, RIGHTEOUS, GOOD, and evil cannot come into His presence, and that is precisely what will happen if we die in our sins and God will do to everyone given to a life sin instead of total righteousness that is only found in God.
Righteousness God gives us is why we can be saved. He didn't have to do that, He was wholly justified not doing it, but He loved us, so He has given us a chance to be redeemed by Him; nothing short of God in us redeems us.
So we repent, we give our lives to God, you have us doing nothing because God must accept us without conditions; your doctrine is justification by God to unrepented sinners who don't love each other or God.
