Notice that this psalm is almost a word-for-word repeat of Psalm 40:14-18. Yahweh is God’s ‘proper name,’ setting him apart from the gods (Elohim) of the nations he easily defeated, whether they were the gods of Egypt or Babylon. The Exodus and the return from Babylon have shown this to be true. Christians continue to use the same name: Jesus (Yehoshua) means ‘Yahweh is Savior.’ He is the Lord we are called to acknowledge (1 Jn 4:15).
When we want to pray for ourselves or others, we can turn to this psalm for guidance.
Regardless of our needs or struggles, the Gospels tell us that Jesus is the answer.
