It’s interesting and worth noting how the psalmist can “praise his word” and repeatedly state that his posture in such praise is trust in God.

Sure, people can “praise God’s word” in a distorted way that forgets the triune God himself, turning words into a tool to some other end. The crafty can use God’s word as currency. Here, however, the Psalmist praises God’s word and trust in God himself.

This is a whole-hearted posture. God’s instruction isn’t questioned as overreaching or restrictive (Gen 3:1–6); it’s praised as good. God’s word isn’t abstracted from his person and used as a means to get what the psalmist really wants, something other than God himself.

The psalmist praises God’s word while his hope and trust, his allegiance, has a living object, God himself. It’s almost as though “Word” is a way of speaking about God himself.
