We love God’s sovereignty for it’s certainty; He is powerful to do the pleasure of His will. We love God’s wisdom for it’s breadth and length and depth; He works and weaves all the threads in perfect purpose. And in God’s omnipotence and omniscience He loves to display His mercy.
The great doxology–perhaps the greatest in all Scripture–at the end of Romans 11 ties a bow on the revelation of God’s work among Israel and the nations, and especially how God shows mercy to the disobedient. Many Jews disobeyed in order that the gospel mercies might go to the Gentiles, and the mercy shown to the Gentiles works toward future mercy to Jews. “For God has consigned all to disobedience, that He may have mercy on all” (Romans 11:32).
Remember back to Romans 9, and Paul’s explanation about God’s glory in election. “For (the LORD) says to Moses, ‘I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.’ So then it depends not on human will or exertion, but on God, who has mercy” (Romans 9:15-16). God is rich in mercy (see Ephesians 2:4).
So two exhortations to confession:
1) Any failure to praise God’s mercy is disobedience. Confess your failure to praise the fulness of His kindness.
2) Any disobedience is a reason to confess your disobedience and pray to God for His mercy. Confess your sin as part of your worship; seeking His mercy honors Him.
And then by the mercies of God present your bodies as a living sacrifice (Romans 12:1). To Him be glory for His mercy forever.
