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.'
God not only giveth us grace, but adopteth us as sons. He not only accounteth us, but He maketh us sons; He maketh us sons, not outwardly, but inwardly; not by inward grace only, but by His Spirit: not only by the birth from the Spirit, but in the Only-Begotten Son; sons of God, because members of Christ, the Son of God; sons of God, by adoption, as Christ is by Nature; but actual sons of God, as Christ is actually and eternally the Son of God. God is our Father, not by nature, but by grace; yet He is really our Father, since we are born of Him, “sons of the living God,” born of the Spirit. He giveth us of His Substance, His Nature, although not by nature; not united with us, (as it is, personally, with His Son,) but dwelling in us, and making us “partakers of the Divine Nature.” “Sons of the living God” must be living by Him and to Him, by His life, yea, through Himself living in them, as our Saviour saith, “If any man love Me, he will keep My words, and My Father will love him, and We will come unto him, and make Our abode with him” John 14:23.
