Yet the number of the children of Israel will be as the sand of the sea, which can't be measured nor numbered; and it will come to pass that, in the place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.'
It shall be said, ye are the sons of the living God - It was the special sin of Israel, the source of all his other sins, that he had left the “living God,” to serve dead idols. In the times of the Gospel, not only should he own God as his God, but he should have the greatest of all gifts, that the living God, the fountain of all life, of the life of nature, of grace, of glory, should be his Father, and as being his Father, should communicate to him that life, which he has and is. For He who is life, imparts life. God doth not only pour into the souls of His elect, grace and faith, hope and love, or all the manifold gifts of His Spirit, but He, the living God, maketh them to he His living sons, by His Spirit dwelling in them, by whom He adopteth them as His sons, through whom He giveth them grace. For by His Spirit He adopteth them as sons. “We have received the spirit of adoption of sows, whereby we cry, Abba, Father. And if sons, then heirs; heirs of God and joint-heirs of Christ” Romans 8:15.
