How does God's purpose relate to the river of God?

The river of God, as depicted in Psalm 65:9, represents God's eternal purpose of grace that flows from Him to water and enrich His creation. This river nourishes the garden He planted in Eden, illustrating that nothing grows apart from the sustenance provided by God. The imagery of the river going forth into the world signifies how His purpose extends beyond Israel, reaching all His chosen ones. In Genesis 2:10, the river's division into four heads symbolizes the spreading of God's grace and purpose throughout the earth. It underscores that God's intention is not just to save but to lavishly provide for His people through His unchanging purpose.
