III. The invitation God gives them to return to him (v. 22): Return, you backsliding children. He calls them children in tenderness and compassion to them, foolish and froward as children, yet his sons, whom though he corrects he will not disinherit; for, though they are refractory children (so some render it), yet they are children. God bears with such children, and so much parents. When they are convinced of sin (v. 21), and humbled for that, then they are prepared and then they are invited to return, as Christ invites those to him that are weary and heavy-laden. The promise to those that return is, "I will heal your backslidings; I will comfort you under the grief you are in for your backslidings, deliver you out of the troubles you have brought yourselves into by your backslidings, and cure you of your refractoriness and tendency to backslide." God will heal our backslidings by his pardoning mercy, his quieting peace, and his renewing grace.
