Psalm 21 — Thanksgiving and Trust

Psalm 21 reveals Christ's kingdom, and the power of his judgment, and his coming again in the flesh to us and the summoning of the nations

Athanasius, On the Interpretation of the Psalms

This psalm is like an response to Psalm 20's anticipation of God's promised support. Both trust in victory and both are royal psalms.

 More importantly in our understanding, is that the king serves as a model for individual believers and their relationships with God. Reading this psalm do we see ourselves trusting God's strength and unfailing love?

I look at this fragment and wonder who used it in prayer,
who was inspired by it, how long has it been used?
It's another reminder of the timelessness of the psalms.

Psalm 20. Contemporary Significance.

Characteristic of Israelite kingship was a tension that most of us face almost daily. If you look at the early narratives of the origins of Israel's monarchy, this tension is very apparent. The Kings constantly struggled with competing demands. On the one hand, the people wanted them to become political and military leaders winning victories against Israel's enemies. On the other hand, God  called them while demanding them to forego the normal kingly reliance on military, political, and financial power in order to lead the people in the ways of Yahweh. [...] Rather than the usual forms of kingly power, therefore, the kings were required to bind themselves to keep the law of Yahweh and to rely on him alone.
