The Holy Spirit is never referred to as an "it," but always a "he." In John 14:15-17 Jesus said: "If you love me, obey my commandments. And I will ask the Father, and he will give you another Advocate, who will never leave you. HE is the Holy Spirit, who leads into all truth. The world cannot receive HIM, because it isn’t looking for HIM and doesn’t recognize HIM. But you know HIM, because HE lives with you now and later will be in you." The Holy Spirit is a person! And no ordinary person, but as we discovered earlier, the Holy Spirit is an eternal person!
I would like to go back to John 15, and close with what the Holy Spirit does for us. Jesus said that the Holy Spirit would be our "advocate." Other translations say encourager, comforter, or counselor. The original Greek word there is "paraclete." This word meant to "come alongside of." This is what God the Holy Spirit does for believers. He comes alongside believers. This is truly amazing. The God of the universe loves us and cares for us enough to come alongside each of us. He comes alongside us and comforts us when we need comfort, encourages us when we are discouraged, strengthens us when we are tempted, and convicts us of our sin when we straying from Him. This truly is amazing. We need to realize this, and bring everything to Him, for the Holy Spirit is the eternal person of God who comes alongside us. If we truly believe this, the way we live should be different than the world! We need to hold on to this amazing truth. Our God is with us always!
