Jesus redeemed the sins of the world by dieing for our sins he granted us the grace for reconciliation back to God, his death has granted us many things by the grace given to us by faith lest any man should boast.
Grace is a gift from God. There are those who simply define grace as "God’s unmerited favor." While this is a truthful definition in that there is nothing we can do to deserve God’s favor, this definition is incomplete.
