III. They fairly promise that they will be governed by the will of God, as soon as they know what it is (v. 5, 6), and they had the impudence to appeal to God concerning their sincerity herein, though at the same time they dissembled: "The Lord be a true and faithful witness between us; do thou in the fear of God tell us truly what his mind is and then we will in the fear of God comply with it, and for this the Lord the Judge be Judge between us." Note, Those that expect to have the benefit of good ministers' prayers must conscientiously hearken to their preaching and be governed by it, as far as it agrees with the mind of God. Nothing could be better than this was: Whether it be good, or whether it be evil, we will obey the voice of the Lord our God, that it may be well with us. 1. They now call God their God, for Jeremiah had encouraged them to call him so (v. 4): I will pray to the Lord your God. He is ours, and therefore we will obey his voice. Our relation to God strongly obliges us to obedience. 2. They promise to obey his voice because they sent the prophet to him to consult him. Note, We do not truly desire to know the mind of God if we do not fully resolve to comply with it when we do know it. 3. It is an implicit universal obedience that they here promise. They will do what God appoints them to do, whether it be good or whether it be evil: "Though it may seem evil to us, yet we will believe that if God command it it is certainly good, and we must not dispute it, but do it. Whatever God commands, whether it be easy or difficult, agreeable to our inclinations or contrary to them, whether it be cheap or costly, fashionable or unfashionable, whether we get or lose by it in our worldly interests, if it be our duty, we will do it." 4. It is upon a very good consideration that they promise this, a reasonable and powerful one, that it may be well with us, which intimates a conviction that they could not expect it should be well with them upon any other terms.
