“I have said all these things to you to keep you from falling away. They will put you out of the synagogues. Indeed, the hour is coming when whoever kills you will think he is offering service to God. And they will do these things because they have not known the Father, nor me. But I have said these things to you, that when their hour comes you may remember that I told them to you. I did not say these things to you from the beginning, because I was with you. But now I am going to him who sent me, and none of you asks me, ‘Where are you going?’ But because I have said these things to you, sorrow has filled your heart. Nevertheless, I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Helper will not come to you. But if I go, I will send him to you. And when he comes, he will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer; concerning judgment, because the ruler of this world is judged. I still have many things to say to you, but you cannot bear them now. When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. He will glorify me, for he will take what is mine and declare it to you. All that the Father has is mine; therefore I said that he will take what is mine and declare it to you." John 16:1-15
Jesus multiple times promises to send the Holy Spirit. In this passage we learn a lot about the Holy Spirit's purpose, and we see that He is a person, a part of the Triune God.
It is best for us that Jesus is in Heaven so that the Holy Spirit could be sent so that the Triune God could live inside everyone of His people. It is easy to think that it would be better if we had Jesus right here next to us, but we have it so much better! God live in us, leading us, guiding us, convicting us, molding us and making us more like Christ every day.
Because we have the Holy Spirit there is no reason to be afraid or anxious over anything. When we are in need we can cry out, "HELP!" We can go straight to God and seek Him first. The Holy Spirit reminds us of God's Words so we can pray God's promises to Him and our hearts can be comforted.
The Holy Spirit is such a gift to God's people. What would it look like to fully rely on and listen to the Holy Spirit?
