I am not sure what the rest of your question was...but God's grace is what gives us forgiveness! The best part is no matter what ...we will always be forgiven.
We stand in the work that was done on the cross when Christ said, "it is finished". the best part is- we don't have to earn it- we just receive it. That is why it is grace- because it is free and unearned.
Ephesians 1:6-8 (New International Version)
To the praise of his glorious grace, which he has freely given us in the One he loves. In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace that he lavished on us with all wisdom and understanding.
