1 "Don't let your hearts be troubled. Trust in God, and trust also in me. 2 There is more than enough room in my Father's home. If this were not so, would I have told you that I am going to prepare a place for you? 3 When everything is ready, I will come and get you, so that you will always be with me where I am. 4 And you know the way to where I am going."
5 "No, we don't know, Lord," Thomas said. "We have no idea where you are going, so how can we know the way?"
6 Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me. 7 If you had really known me, you would know who my Father is. From now on, you do know him and have seen him!"
8 Philip said, "Lord, show us the Father, and we will be satisfied."
9 Jesus replied, "Have I been with you all this time, Philip, and yet you still don't know who I am? Anyone who has seen me has seen the Father! So why are you asking me to show him to you? 10 Don't you believe that I am in the Father and the Father is in me? The words I speak are not my own, but my Father who lives in me does his work through me. 11 Just believe that I am in the Father and the Father is in me. Or at least believe because of the work you have seen me do.
12 "I tell you the truth, anyone who believes in me will do the same works I have done, and even greater works, because I am going to be with the Father. 13 You can ask for anything in my name, and I will do it, so that the Son can bring glory to the Father. 14 Yes, ask me for anything in my name, and I will do it!"
There is but ONE God: God the Father, God the Son, God the Holy Spirit. He is neither one, nor the other, but ALL at once.
God is spirit. God sent Himself down to earth in the form of man as God the Son, Jesus Christ, the one true Messiah. God is our Savior. God sacrificed Himself for us. God in Heaven, God the Father --of which we all have access by knowing and accepting Jesus Christ as our Messiah -- gives us God the Holy Spirit, our Advocate, through our relationship with Jesus Christ.
God the Father, God the Son, and God the Holy Spirit created the universe, and all in it. It is part of His perfect plan, carried out through His three Personalities, though He is but One God. We need Jesus in order to gain access to God, and therefore need Jesus in order to receive the Holy Spirit. This is why: Jesus performed the ultimate in sacrifices for our eternal souls. God cannot be in the presence of sin, because He is HOLY. By the spilling of Jesus' blood, he atoned for all sins of all mankind, creating a clean slate for us before God. We, therefore, cannot be clean without Jesus. He is our Mediator. He speaks on our behalf to the Father. Jesus, God the Son, is the only way we can be forgiven by God the Father, who reveals Himself through God the Holy Spirit -- the Leader into all truth, God's truth.
