After these judgments the Lord would deal with Israel ( Jews & Gentiles ) more gently by the promise of rest in Christ we are invited to take His yoke upon us, and the work of conversion may be forwarded by comforts, as well as by convictions of earthly joy, and help from ourselves, that, being shut from every other door, we may knock at mercy’s gate. That was the message of the Prophet Hosea 2: 23.
The Lord, Our God vows to have mercy both on the Jews & Gentiles who shall obey the Gospel call, and become true converts to the Christian faith. This was part fulfilled in Romans 9: 24 – 26 “…Those who were not my people, I will now call my people. And I will love those whom I did not love before; And, at the place where they were told, You are not my people, there they will be called ” Children of the living God. “
Perhaps, ” And they shall say, thou are my God ” – There seems to be more affectionateness in the brief, answer, which sums up the whole relation of the creature to the creator in that one Word ” Elohai, my God “. The prophet declares as before, that when God thus Anew called them His people, they by His grace would obey His call, and surrender themselves wholly to Him.
For to say ” my God, is to own an exclusive relation to God alone. It is to say, my beginning and my end, my hope and my Salvation, my whole and only good, in whom Alone; I will hope, whom alone I will fear, love, worship, trust in, obey and serve with all my heart, mind, soul, and strength, my God and my All.
