O give thanks unto the LORD; for he is good; for his mercy endureth for ever. 1 Chronicles 16:34
It is only the believing sinner that has an interest in sovereign mercy. Those who imagine themselves to be righteous within themselves find the infinite mercy of our sovereign God to be quite offensive. But the child of God has been made to know by the grace of God that he is in desperate need of the mercy of God all the time. We understand that if God, for one split second, ceased to be merciful, we would perish without his Son and without recovery. I will be merciful is the ETERNAL WORD OF GOD! This declaration is more than prophetic.
God is declaring that he will be FOREVER MERCIFUL! God must be merciful, because mercy is his very nature—He has declared it. God has chosen, by necessity of his character, to manifest his mercy for sinful man in the Lord Jesus Christ. It is in the eternal Son of God, who was manifest as the eternal Son of Man, that we poor sinners are objects of infinite mercy. I will be merciful was not God’s declaration made first in time, but in eternity. This is his oath made to his Son in the eternal covenant of grace before the world was and repeated unto Moses for the assurance and comfort of all the elect of God. There is no mercy for fallen creatures apart from the person and work of God’s appointed substitute, the Lord Jesus Christ. He is our MERCY SEAT!
