'Grace of God' in the Bible

Who, when he came and saw the grace of God, was glad; and he made clear to them the need of keeping near the Lord with all the strength of their hearts:

Now when the meeting was ended, a number of the Jews and of the God-fearing Gentiles who had become Jews, went after Paul and Barnabas: who put before them how important it was to keep on in the grace of God.

And from there they went by ship to Antioch, where they had been handed over to the grace of God for the work which they had not done.

But I put no value on my life, if only at the end of it I may see the work complete which was given to me by the Lord Jesus, to be a witness of the good news of the grace of God.
