Verse 28. My mercy will I keep for him for evermore. The kings of David's line needed mercy, and mercy prevented their house from utterly perishing until the Son of Mary came. He needs no mercy for himself, but he is a representative man, and the mercy of God is required for those who are in him: for such mercy is kept for ever.
And my covenant shall stand fast with him. With Jesus the covenant is ratified both by blood of sacrifice and by oath of God, it cannot be cancelled or altered, but is an eternal verity, resting upon the veracity of one who cannot lie. What exultation fills our hearts as we see that the covenant of grace is sure to all the seed, because it stands fast with him with whom we are indissolubly united.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 28. My mercy will I keep for him for evermore. How will he keep his mercy for Christ for evermore? Very simply, I think. Is not Christ the Fountain of all mercy to us? Is it not the mercy of God the Father flowing to us through Christ that we enjoy? Is he not the Depository of it all? God says, then, I will keep it for him; for ever and ever shall it be lodged in Christ, and Isis people shall enjoy it throughout eternity. --Capel Molyneux, 1855.
Verse 28-30. Here is comfort to those who are true branches, and continue to bring forth fruit in the midst of all the trials that befall them, that God will not suffer them to be cut off by their corruption. If anything in them should provoke God to do it, it must be sin. Now for that, you see how Christ promises that God will take order therewith, and will purge it out of them. This is the covenant made with David, (as he was a type of Christ, with whom the same covenant is made sure and firm,) that if his seed forsake my law, and walk not in my judgments, -- What! presently turn them out of doors, and cut them off, as those he meant to have no more to do with? What! nothing but utter rejection? Is there no means of reclaiming them? Never a rod in the house? Yes -- then will I visit their transgression with the rod, and their iniquity with stripes, whip out their stubbornness and sinfulness; but my loving kindness will I not utterly take from him as I did from Saul, as it is in 1 Chronicles 17:13 .
Let the saints consider this, that they may return when they are fallen, and submit to him and his nature, and suffer him to do what he will with them, and endure cutting, and lancing, and burning, so long as he cuts them not off; endure chastening, and all his dealings else, knowing that all the fruit is but to take away the sin, to make them "partakers of his holiness"; and "if by any means", as Paul speaks of himself, ( Philippians 3:11 ), be the means what it will, it is no matter. And God, if at any time he seems to cut thee off, yet it is but as the incestuous Corinthian was cut off, `that the flesh might be destroyed, and the spirit saved.' --Thomas Goodwin.
