'Grace of God' in the Bible

For our reason for boasting is this: the testimony of our conscience that we conducted ourselves in the world, and especially toward you, in holiness and purity of motive from God, not in merely human wisdom, but by the grace of God.

Now [because we] are fellow workers, we also urge you not to receive the grace of God in vain.

Now we make known to you, brothers, the grace of God that has been given among the churches of Macedonia,

and [they are] longing for you in their prayers for you, because of the surpassing grace of God to you.
