3. The manner in which this covenant shall be made. (1.) In righteousness and judgment, that is, God will deal sincerely and uprightly in covenant with them; they have broken covenant, and God is righteous. "But," says God, "I will renew the covenant in righteousness." The matter shall be so ordered that God may receive even these backsliding children into his family again, without any reflection upon his justice, nay, his justice being satisfied by the Mediator of this covenant very much to the honour of it. But what reason can there be why God should take a people into covenant with him that had so often dealt treacherously? Will it not reflect upon his wisdom? "No," says God; "I will do it in judgment, not rashly, but upon due consideration; let me alone to give a reason for it and to justify my own conduct." (2.) In lovingkindness and in mercies. God will deal tenderly and graciously in covenanting with them; and will be not only as good as his word, but better; and, as he will be just in keeping covenant with them, so he will be merciful in keeping them in the covenant. They are subject to many infirmities, and, if he be extreme to mark what they do amiss, they will soon lose the benefit of the covenant. He therefore promises that it shall be a covenant of grace, made in a compassionate consideration of their infirmities, so that every transgression in the covenant shall not throw them out of covenant; he will gather with everlasting lovingkindness. (3.) In faithfulness. Every article of the covenant shall be punctually performed. Faithful is he that has called them, who also will do it; he cannot deny himself.
