Shared ground
Psalm 43:4 presents a future-looking promise: once God’s leading and restoration happen (linked by “then”), the speaker expects to return to proper worship. The “altar of God” is named as the destination, and the response is active praise, including music (“harp”).
The verse also makes a clear relational claim. God is not only the place one goes to worship; God is described as “my exceeding joy,” and the line ends with direct address, “God, my God.” That closing phrase highlights personal belonging and renewed closeness, not mere ritual.
Where interpretation differs
Some readers take “altar” as a literal sanctuary location where offerings are brought. Others think it can also work as poetic shorthand for restored access to worship, whether or not the speaker is describing a specific moment at a specific altar.
There is also a smaller question about the “harp”: some read it as indicating organized, public sanctuary music, while others allow for the picture of personal praise that still fits Israel’s worship culture.
Why the disagreement exists
The language is concrete (altar, harp), which points naturally to physical worship practices. At the same time, Psalms regularly use worship-space language to express spiritual reality (nearness, restored relationship), so interpreters differ over how tightly to tie the imagery to one setting.
What this passage clearly contributes
Explicitly, the text ties renewed worship to God’s restoring guidance (“then”). It frames worship as both location-linked (“altar”) and relationship-centered (“to God, my exceeding joy”). It depicts praise as embodied and audible (music), and it emphasizes personal attachment in worship (“God, my God”).
