'Grace of God' in the Bible

Who, coming, and seeing the grace of God, rejoiced, and continued to exhort all, with purpose of heart to abide with the Lord:

And the synagogue having been adjourned, many of the Jews and pious proselytes followed Paul and Barnabas, who, speaking with them, continued to persuade them to abide in the grace of God.

and thence they sailed away into Antioch, whence they had been committed to the grace of God for the work which they fulfilled.

But I consider my life worthy of no consideration to myself, so as to finish my course, and the ministry which I received from the Lord Jesus, to bear testimony to the gospel of the grace of God.
