Mercy and truth are met together; righteousness and peace have kissed each other.
Mercy and truth are met together. "Mercy" from God for the pardon of our sin is shown, in the redemption performed by Messiah for Israel literal and spiritual, to harmonize with the "truth" of God - i:e., with His faithfulness alike to His threatening against sin and to His promise of salvation notwithstanding to lost man. For Christ hath suffered the threatened penalty; therefore Christ's people receive the promised mercy.
Righteousness and peace have kissed each other. The demands of God's righteousness against man were met by the Saviour's meritorious death as man for man; so "peace" to man is reconciled with the unimpaired glory of God's righteousness. The meeting and the kissing of each other (Psalms 85:10-11) imply that there had been in appearance a separation of these attributes respectively, which now are showed to harmonize (Isaiah 42:21); so that every true Israelite can say, "In the Lord have I righteousness and strength ... in the Lord shall all the seed of Israel be justified, and shall glory" (Isaiah 45:24-25).
