Which knoweth the hearts; God knew the desires of the Gentiles, that they did sincerely desire to please God, and to see this salvation. This great attribute David improved, 1 Chronicles 29:17, and highly recommended his son Solomon to consider of, 1 Chronicles 28:9; which, if believed, would make us also to serve God with a perfect heart and a willing mind. Giving them the Holy Ghost; God himself was a witness for these Gentiles beyond all exception, when he gave them the ordinary and extraordinary gifts of the Holy Ghost; by which he testified, that they belonged to Christ, whose Spirit this was. Thus the testimony of Jesus is the spirit of prophecy, Revelation 19:10; and the Spirit, according to our Saviour's promise, 1 Thessalonians 15:26, doth testify of him.
