What does the Bible say about the river of God?

In Psalm 46:4, the river of God is depicted as crucial for the city of God, with its streams bringing gladness. This refers to God Himself who is in the midst of His Church and provides a continuous source of spiritual sustenance. As Ralph Erskine noted, the river symbolizes God in His fullness—the Father as the fountain of living waters, the Son as the Savior who brings healing and cleansing, and the Holy Spirit who regenerates and empowers believers. Thus, this river signifies the divine presence and the abundant grace flowing from God to His people.
