V. That God would renew his covenant with them, would be faithful to them and make them so to him: They shall be my people and I will be their God. That is the foundation and crown of all these promises, and is inclusive of all happiness. They shall obey God's laws, and God will secure and advance all their interests. This contract shall be made, shall be new-made, in truth and in righteousness. Some think that the former denotes God's part of the covenant (he will be their God in truth, he will make good all his promises of favour to them) and the latter man's part of the covenant—they shall be his people in righteousness, they shall be a righteous people and shall abound in the fruits of righteousness, and shall not, as they have done, deal treacherously and unjustly with their God. See Hos. ii. 19, 20. God will never leave nor forsake them in a way of mercy, as he has promised them; and they shall never leave nor forsake him in a way of duty, as they have promised him. These promises were fulfilled in the flourishing state of the Jewish church, for some ages, between the captivity and Christ's time; they were to have a further and a fuller accomplishment in the gospel-church, that heavenly Jerusalem, which is from above, is free, and is the mother of us all; but the fullest accomplishment of all will be in the future state.
