The spirit world and the Lord.

Jonathan Edwards wrote an old book, called ‘”The Experience That Counts” (Experience of God). He was absolutely correct, as, without the experience of God, you cannot know Him, nor walk with Him.
Book learning and theology go but so far, but WILL NOT make someone a disciple, nor give them the authority of God in Christ. No – it is only God who chooses and sends those whom He wishes to teach, and do His work!
