Psalms 84:11

Forasmuch then as our turning away from God is our own act, and this is evil will; but our turning to God is not possible, except He rouses and helps us, and this is good will, what have we that we have not received? But if we received, why do we glory as if we had not received? Therefore, as “he that glorieth must glory in the Lord,” it comes from His mercy, not their merit, that God wills to impart this to some, but from His truth that He wills not to impart it to others. …

6. Thus also most pertinently may be understood, “let the mountains bear peace to the people,” namely, that we understand the peace to consist in the reconciliation whereby we are reconciled to God: for the mountains receive this for His people.…“Let the mountains, therefore, receive peace for the people, and the hills justice:” so that in this manner, both being at one, there may come to pass that which hath been written, “justice and peace have kissed one another.” But that which other copies have, “let the mountains receive peace for the people, and let the hills:” I think must be understood of all sorts of preaching of Gospel peace, whether those that go before, or those that follow after. …

9. “Mercy and truth have met together” ( ver. 10 ). “Truth in our land,” in a Jewish person, “mercy” in the land of the Gentiles. For where was truth? Where the utterances of God were. Where was mercy? On those who had left their God, and turned themselves unto devils. Did He look down also upon them? Yea, as if He said, Call those who are fugitives afar off, who have departed far from Me: call them, let them find Me who seek them, since they themselves would not seek Me. Therefore, “Mercy and truth have met together: righteousness and peace have kissed each other.” Do righteousness, and thou shalt have peace; that righteousness and peace may kiss each other. For if thou love not righteousness, thou shalt not have peace; for those two, righteousness and peace, love one another, and kiss one another: that he who hath done righteousness may find peace kissing righteousness. …

24. “My truth also and My mercy is with Him” ( ver. 24 ). All the paths of the Lord are mercy and truth. Remember, as much as ye can, how often these two attributes are urged upon us, that we render them back to God. For as He showed us mercy that He might blot out our sins, and truth in fulfilling His promises; so also we, walking in His path, ought to give back to Him mercy and truth; mercy, in pitying the wretched; truth, in not judging unjustly. Let not truth rob you of mercy, nor mercy hinder truth: for if through mercy you shall have judged contrary to truth, or by rigorous truth shall have forgotten mercy, you will not be walking in the path of God, where “mercy and truth meet together.” “And in My name shall His horn be exalted.” Why should I say more? Ye are Christians, recognise Christ.

3. Think how great that weeping must be which deserves to be compared to a flood of waters. Whosoever so weeps and says with the prophet Jeremiah “let not the apple of mine eye cease” shall straightway find the words fulfilled of him: “mercy and truth are met together: righteousness and peace have kissed each other;” so that, if righteousness and truth terrify him, mercy and peace may encourage him to seek salvation.
