John 16:15: “All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.”
Here the Spirit is seen in complete submission to and in harmony with the Son and the Father. He does not act or speak from Himself. Nothing originates from Him; all comes from the Son, and all is done to glorify the Son. Just as the Son did not do anything from Himself, but only that which He heard and received from the Father, so the Spirit never acts independently from the Son. The Spirit’s function is to reveal the Son in all that He is to believers. Yet, in revealing the Son, the Spirit is actually revealing the Father because all that the Son has comes from the Father. Thus, the Spirit reveals the Son, who, in turn, expresses the Father. It is a clear revelation of the mutual interdependency of the Trinity.
Another emphasis in 16:15 is that the Holy Spirit discloses Himself through the Scriptures. This means you and I must be in the Word in order to hear the words of the Father and the Son. Have you ever walked in the dark along an unfamiliar path without any illumination except a flashlight? A flashlight allows you to see a few feet—not a few miles—ahead of you. It provides just enough light so that you can see clearly to take the next step. In the same way, God rarely provides us with enough light to see every step we need to take in the future (perhaps so that we are not tempted to run ahead of Him). But He promises to give us enough direction to take the next step. This is why the Psalmist says God’s Word is a “light” not a “floodlight” to my path. In like manner, who among us really wants to know what the future holds? If God were to reveal our future, many of us would be aghast at what calamities and/or diseases await us. We must walk with God in His Word step by step. The Holy Spirit will enable us to do this for He is a God send.
When I was growing up, my dad functioned like the Holy Spirit in my life. On our road trips and throughout my life he protected me, he provided for me, he guided me, and he cared for me. In the same way, the Holy Spirit will protect you, provide for you, guide you, and care for you. All you have to do is ask for His help. He will then empower you to live the abundant life here on earth (10:10), and then He will take you on a journey to a Heavenly destination. All it takes is the faith of a child to believe in Him and place your trust in His ability to take you home. The Holy Spirit is a God send.
