Jeremiah prays on behalf of Judah, and he begins the prayer with an admission that what he is about to ask, his people have no right to request. He starts with an admission of Judah’s sin, sin which is extensive and prolonged – ‘our backslidings are many.
Prayer sometimes requires us to reason like this with the Lord. We are not telling him anything that he does not already know, of course, but he exercises our faith and waits to see us plead with him on the basis of what he has revealed about himself. But this is especially necessary in the case of the backslider. He knows with great clarity that he is unworthy He feels that he may have gone too far, and that God will never hear him again. And yet he knows that he can find help in none other than the Lord. He hangs on every word of God, and searches diligently for the slightest encouragement he can derive from what God has said. Has God absolutely said that his ears are shut to our prayers. Grace is very great – is it great enough for my case? Jeremiah prays on behalf of the people, praying as we ought to pray – with humility, with honesty, attributing righteousness and justice to God, without excuse, without self-justification, keeping in mind the mercy of God though we cannot see it now, reminding God of his promises, binding him to his own faithfulness, arguing from his attributes and not from anything in us.
