There was a worship song in the 90’s called ” Let the River flow” by  Darryl Evans, an awesome worship leader. The chorus  sings “Let the river flow, Let the river flow, Holy Spirt come move in power, Let the River flow”.  This swell of music is our beckoning the Spirit, to bring the presence of God since we are yearning for his presence. 

Rev 22:1-2 TLB And he pointed out to me a river of pure Water of Life, clear as crystal, flowing from the throne of God and the Lamb, coursing down the center of the main street. On each side of the river grew Trees of Life, bearing twelve crops of fruit, with a fresh crop each month; the leaves were used for medicine to heal the nations.

When the River Flows, cleansing, healing and sanctification occurs.
