Ephesians 2:8 says, "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast."
God sent Jesus to suffer on the cross, and rise on the third day so that whoever believes in him shall be with him one day, for eternity. There is nothing we can do to earn this eternal life in heaven with him, for that is why it is a gift given to us from God.
