Isaiah 55:6–7 (ESV) … “Seek the Lord while he may be found; call upon him while he is near; let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon.”
Oh! how blessed is it to see the earnestness with which the Lord pleads with his people. The gospel is called the ministry of reconciliation, 2 Cor. 5:18; and this notion carries with it the state of man before the fall, as being a state of amity and friendship. We cannot be said to return to the Lord, but under the idea that there was a time when our nature was in friendship with the Lord; which was indeed the case when Adam came out of the hands of his almighty Creator, pure and holy. But when he fell, all his children fell in him, and with him. Hence, when redemption is proclaimed, in and by Christ, the recovery from sin to salvation is called a return. What a beautiful and gracious invitation, seen in this point of view, doth these verses contain; and how sure of acceptance in Jesus! Psalm 27:8. Ephes. 1:6.
