7 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you.
13 But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14 He will glorify me because it is from me that he will receive what he will make known to you.–John 16: 7, 13,14 NIV
Jesus had been a Friend, Teacher, Mentor, and Guide for the disciples for the better part of 3 years. Now in In preparing His disciples for His departure, Jesus tells them He is leaving for their good. What could possible be better than walking with Jesus? Who would lead them in His absence? Who would talk with them? Who would strengthen and encourage them now? Jesus told them there is an Advocate coming to do all this for them. The Spirit of Truth that would guide them into all truth. Just as Jesus had said about Himself, He also says about the Holy Spirit.
19 Jesus gave them this answer: “Very truly I tell you, the Son can do nothing by himself; he can do only what he sees his Father doing, because whatever the Father does the Son also does.–John 5:19 NIV
Why would this be better? As a human, Jesus could only be in one place at one time. He could only teach those within the sound of His voice. The Holy Spirit is not bound by human restraints. He lives inside of each of us and can be everywhere at once. Just think of it, God’s Powerful Spirit (GPS, if you will) with His own network that reaches everywhere and is never out of contact with you or His home station. Powerful enough to direct every human on earth at one time. So, if you are feeling lost, confused or needing encouragement, just stop and listen to the GPS inside you.
