Passage
Mercy and truth have met each other: justice and peace have kissed.
Mercy and truth have met each other: justice and peace have kissed.
Psalms 84:9 I will hear what the Lord God will speak in me: for he will speak peace unto his people: And unto his saints: and unto them that are converted to the heart.
Psalms 84:10 Surely his salvation is near to them that fear him : that glory may dwell in our land.
Psalms 84:11 Mercy and truth have met each other: justice and peace have kissed.
Psalms 84:12 Truth is sprung out of the earth: and justice hath looked down from heaven.
Psalms 84:13 For the Lord will give goodness: and our earth shall yield her fruit.
The verse centers on "mercy", "truth", "each", "other", "justice", "peace", and "kissed". It is saying that the verse draws attention to "mercy" and "truth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "Surely his salvation is near to them..." into verse 12's "Truth is sprung out of the earth...", so "mercy" and "truth" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "truth" with trust shaped by these words, not by a vague optimism outside the passage.
