Verse 7. He shall abide before God for ever. Though this is true of David in a modified sense, we prefer to view the Lord Jesus as here intended as the lineal descendant of David, and the representative of his royal race. Jesus is enthroned before God to eternity; here is our safety, dignity, and delight. We reign in him; in him we are made to sit together in the heavens. David's personal claim to sit enthroned for ever is but a foreshadowing of the revealed privilege of all true believers.
O prepare mercy and truth, which may preserve him. As men cry, "Long live the king," so we hail with acclamation our enthroned Immanuel, and cry, "Let mercy and truth preserve him." Eternal love and immutable faithfulness are the bodyguards of Jesus' throne, and they are both the providers and the preservers of all those who in him are made kings and priests unto God. We cannot keep ourselves, and nothing short of divine mercy and truth can do it; but these both can and will, nor shall the least of the people of God be suffered to perish.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 7. O prepare mercy. David having declared in his own behalf the purpose of God towards him for everlasting salvation, he, speaking of himself, shall abide before God for ever: he withal considering what he was to run through in this life, and what it might require to keep him unto the end, and so for ever, doth presently thereupon, in way of prayer, subjoin prepare mercy and truth, which may preserve me. As if he had said, I have yet a long journey to go, and through many hazards, and thy promise is, I shall abide before thee for ever. Lord, thou hast need lay up and aforehand prepare an abundance of mercy and truth to preserve me for time to come. Thomas Goodwin.
