Isaiah 43:21 teaches us the reason why God created human beings. "the
people I formed for myself that they may proclaim my praise."
What does God want His people to praise? The previous verse, Isaiah 43:20, has the answer.
"because I provide water in the desert and streams in the wasteland, to give drink to my people, my chosen,"
We people praise God, who is providing water in the desert and streams in the wasteland. As we know, when the word of water comes up in the Bible, it points to Jesus.
Jesus says in John 7:38, "Whoever believes in me....rivers of living water will flow from within him."
Therefore, when we praise God, our soul becomes full of Jesus, and our thirst for the soul will be gone.
Psalm 22:3 sings, "Yet you are enthroned as the Holy One; you are the one Israel praises."
Yes! Jesus is the one we praise. Praise the Lord!
