After Jesus told His disciples, in John 16, that He was going back to the Father, they were sorrowful. Then He told them this in verse 7:
7 However, I am telling you nothing but the truth when I say it is profitable (good, expedient, advantageous) for you that I go away. Because if I do not go away, the Comforter (Counselor, Helper, Advocate, Intercessor, Strengthener, Standby) will not come to you [into close fellowship with you]; but if I go away, I will send Him to you [to be in close fellowship with you].
Jesus said that He MUST leave in order for the Holy Spirit to be given to every born again believer. That was good news in every way! He tells us what this means for the lost in verses 8-11:
8 And when He comes, He will convict and convince the world and bring demonstration to it about sin and about righteousness (uprightness of heart and right standing with God) and about judgment: 9 About sin, because they do not believe in Me [trust in, rely on, and adhere to Me]; 10 About righteousness (uprightness of heart and right standing with God), because I go to My Father, and you will see Me no longer; 11 About judgment, because the ruler (evil genius, prince) of this world [Satan] is judged and condemned and sentence already is passed upon him.
The Holy Spirit does NOT teach the lost about the New Covenant and the deeper things of God! He makes it clear to them that they NEED to be born again! Once they choose to agree with the Word of God concerning that Truth, then they can receive the Spirit of God to live in them and they can grow up! Until then, they will NOT be able to even understand the Word of God, because it is "spiritually discerned" (1 Corinthians 2:14). Now are you ready to see what Jesus promised to those who DO receive Him as Lord and personal Savior? Look at verses 12-14:
12 I have still many things to say to you, but you are not able to bear them or to take them upon you or to grasp them now. 13 But when He, the Spirit of Truth (the Truth-giving Spirit) comes, He will guide you into all the Truth (the whole, full Truth). For He will not speak His own message [on His own authority]; but He will tell whatever He hears [from the Father; He will give the message that has been given to Him], and He will announce and declare to you the things that are to come [that will happen in the future]. 14 He will honor and glorify Me, because He will take of (receive, draw upon) what is Mine and will reveal (declare, disclose, transmit) it to you.
They were not able to understand the Word YET, either! Once they were born again and then filled with the Spirit, (Acts 2), THEN they could begin to understand the Word of God! Jesus said, in verses 12-14 above, that the Holy Spirit would guide them into the Truth! He will YOU, too! Are you READY??? Here is Hillsong United with "Go":
