Psalm 86 is a lonely and remarkable psalm. It is the only psalm of David in Book III of the Psalter, where so many songs wrestle with national ruin and confusion. After Psalm 85’s prayer for the healing of the land, Psalm 86 brings the crisis inward: revival must finally reach a single trembling heart.
What is unusual is that David seems to pray here with borrowed words. This psalm echoes earlier psalms and, most clearly, God’s self-revelation in Exodus 34:6. Some readers might think that makes it less original. It makes it more mature. The deepest prayers are often not the most inventive, but the most inhabited by Scripture. When pain is sharp, the saints do not need cleverness; they need covenant language.
So when David says in verse 15 that God is “compassionate and gracious, slow to anger, abounding in love and faithfulness” (New International Version), he is reaching back to Sinai—to the words God spoke after the golden calf. That matters. David grounds his hope not in a vague belief that God is kind, but in the revealed name of the God who stays with a people who have already failed him.
The center of the psalm is one of the great prayers in all Scripture: “Teach me your way, Lord… give me an undivided heart” (verse 11, New International Version). The Hebrew is even more arresting: make my heart one. This is more than asking for focus. It is a plea for inner healing. We usually think our problem is that we are weak. Psalm 86 says our problem is that we are divided.
We want God, but also applause. Obedience, but also control. Holiness, but also one private corner where Christ may not reign. Augustine saw in this verse the soul being gathered from its scattered loves. Calvin wrote that until God collects our wandering affections, we cannot truly fear him. The Western self often celebrates having many options, many identities, many inner voices. Scripture is less impressed. A fractured heart cannot worship deeply because it is always negotiating with its idols.
Then comes the psalm’s startling horizon: in the middle of personal distress, David says, “All the nations you have made will come and worship before you” (verse 9). In the ancient Near East, nations were thought to belong to their own territorial gods. Archaeology gives us many inscriptions that reflect that world. But David declares something revolutionary: the nations are not owned by idols; they were made by the Lord. His private prayer opens into global hope. Suffering has not made him smaller. It has made him missionary.
Even verse 16 is tender with covenant meaning: “save the son of your maidservant.” This is household language. He is not saying, “Pay me my wages,” but, “Remember I belong in your house.” That is the gospel’s logic too. We do not approach God as contractors, but as sons and daughters in the household of mercy.
Perhaps the truest sign of God’s favor is not immediate escape, but a heart no longer split in two.

Hymn suggestion: Be Thou My Vision
Lord, teach me your way. Gather the scattered pieces of my heart and make it one in the fear of your name. Let your mercy be deeper than my trouble, and your truth stronger than my divided loves. And as you answer me, widen my heart for the worship of all nations through Jesus Christ. Amen.
