The Comforter, or the Holy Spirit, was sent to guide all who believe in Christ and give them the divine power and grace needed to walk the Christian life “Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come (John 16:13).
