They Will Come & Declare His Righteousness
They will come and declare His righteousness to a people who will be born, That He has done this. Psalm 22:31
The generation of the righteous God will graciously own as his treasure, his children. Their agency for him: they shall come, shall rise up in their day, not only to keep up the virtue of the generation that is past, and to do the work of their own generation, but to serve the honour of Christ and the welfare of souls in the generations to come; they shall transmit to them the gospel of Christ (that sacred deposit) pure and entire, even to a people that shall be born hereafter; to them they shall declare two things: -That there is an everlasting righteousness, which Jesus Christ has brought in. This righteousness of his, and not any of our own, they shall declare to be the foundation of all our hopes and the fountain of all our joys. See Rom. 1. 16, 17. -That the work of our redemption by Christ is the Lord's own doing (Ps. 118:23) and no contrivance of ours. We must declare to our children that God has done this; it is his wisdom in a mystery; it is his arm revealed.
In singing this we must triumph in the name of Christ as above every name, must give him honour ourselves, rejoice in the honours others do him, and in the assurance we have that there shall be a people praising him on earth when we are praising him in heaven. - Matthew Henry
