The river that flows forth from paradise is the river of life. Where is paradise today? Paradise is in heaven. Jesus said that the kingdom of God is within. The believer is connected to heaven from within. It is God who is within. It is from this well and this spring that the Earth is watered with the influences of heaven through the believer.
It is violent. Jesus said that the anointing breaks the yoke. He also said that the kingdom of God advances violently, and violent men lay hold of it. So, faith is believing in the unseen and laying hold of it – seeing with the eye of faith and acting accordingly.
