For it is by grace that you have been saved, through faith - and this is not from yourselves, it is the gift of God - not by works, so that no-one can boast.
The word grace means "undeserved favour". It means that God is offering you something you could never provide for yourself. Forgiveness of sins and eternal life. God's gift to you is free. You do not have to work for a gift. All you have to do is joyfully receive it. Believe with all your heart that Jesus died for you.
