Ephesians 2:4-9; Romans 3:24; Acts 15:11

But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ - by grace you have been saved - and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. 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. 

and are justified by his grace as a gift, through the redemption that is in Christ Jesus,

But we believe that we will be saved through the grace of the Lord Jesus, just as they will. (ESV)
