One of the most important things Jesus ever said was: "You will receive power when the Holy Spirit has come upon you; and you will be My witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
Rivers of living water
Jesus said, ‘He that believeth on Me, out of his inner being shall flow rivers of living water.’ The Holy Spirit is the source, but the Word of God says that when we have received the Holy Spirit, the source is in us! External experiences are of the world, the flesh or the devil. The inner experience is the fresh river source, the sweet blessing, the mighty power of God, the Holy Spirit within you!
