'By Grace' in the Bible

But not as the transgression, so also [is] the gift. For if by the transgression of one the many became dead, much more the grace of God, and the gift by grace, which is in that one man, Christ Jesus, hath abounded unto many.

But if by grace, it is no more by works: otherwise grace is no more grace. But if by works, it is no more grace: otherwise work is no more work.
