The logic of grace

The darkest, sickest person can be saved. Almost every sin has been forgiven at one point or another in the bible. God wants every heart to repent even in the most heinous of men. He does not want any person to experience hell. I almost believe that repentance is the act of you deciding whether God loves you or not. You actually get to make the decision of whether you're going to hell or not. If repentance forgives all things then therefore the choice is all yours. God loves us all enough that he sent us a Messiah, a way out of darkness, and every form of it. King David killed his servant Uriah and married his wife. Although there was a price for his sin(his son having to die), God still saved his soul and still considered him a blessed one. This is an example of how deep God's grace is. Jesus was crucified with two robbers. One of them had faith enough to ask for his mercy and he was granted eternal life on the cross. Jesus showed mercy and compassion to the woman at the well who had had five husbands. God forgave Paul of blasphemy and bigotry and maybe even (or more than likely) murder. He erased the sins of Mary Magdalene( A WHORE) and showed her mercy before all men. The grace of god is very deep. There is no end to it if you repent,. but if you don't you can possibly lose your salvation.If we are always saved, why do we need to worry about sin, Ever? Why do we need to repent. This is why the theology of once saved always saved does not work. If we"re fine then, why can't we go out and rob a bank,if we have immunity from sin. The bible says we're still going to sin after we're saved. The bible tells us that we need to work out our salvation with fear and trembling. Why would we need to have fear and quake if we are permanently sealed? It is not o.k to sin, ever!! But God is Just to forgive it.
