God is merciful and quick to forgive.

Good News Bible: Isaiah 55: 6 and 7

⁶Turn to the Lord and pray to him, now that he is near.  ⁷Let the wicked leave their way of life and change their way of thinking. Let them turn to the Lord, our God; he is merciful and quick to forgive.

The most dangerous lie that we can believe is that God cannot (or will not) forgive us. Those that say, "I am too far gone" and "I cannot change” have fallen into this trap. It is true that our sinfulness before God is great. Scripture tells us (Rom 3: 23) that “everyone has sinned and is far away from God's saving presence”.  Some recognize this truth, yet draw the wrong conclusion from it saying:  “I am beyond redemption”. 

No, our God is so great that there is nobody this side of the grave that is too far gone, or beyond hope.

The right conclusion is that we should throw us upon the LORD for his mercy and forgiveness, by turning to him and praying to him. Because as we turn to God, we turn away from wickedness and when we pray to him, we will see his mercy and experience that he is quick to forgive.  God is not waiting for us to sin that he can smite us, but he is waiting for us to turn to him that he can bless us with his mercy and pardon.
