The kingdom of God is … in the Holy Spirit. Romans 14:17
How Jesus established His kingdom in the Spirit
Since, the kingdom of God is in the Spirit; Jesus asked His Father to pour out the Holy Spirit (Jn 14:26, Lk 24:49) so we, and those who came before us, could enter the kingdom (Jn 3:5-8, Ro 8:9).
Jesus did not began His public ministry until He was baptized with water and the Spirit (Mt 3:16-17, Acts 10:34-38) and tempted by the devil (Mt 4:1-11). After withstanding the temptations, Jesus began His ministry, preaching the kingdom with signs following (Mt 4:12-17).
As was prophesied, Jesus went to the cross of crucifixion with His face set like flint.(Isaiah 50; Matthew 27:26-31; Mark 15:16-20; Luke 22:63-65; John 19:1-15) Jesus was crucified as an offering for our sin.
By His righteousness, we are justified, for He bore our iniquities and the iniquities of those who have gone before us.
Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities. Isaiah 53:10-11 KJV
Jesus was crucified (Ps 69:1-36; Mk 15:21-32; Lk 23:26-43; Jn 19:16-27). By His sacrifice, the blood of Jesus cleanses us from all sin (1Jo 1:7).
Jesus rose from the dead (John 20). He was raised by the Father’s glory. “Or don’t you know that all of us who were baptized into Christ Jesus by our baptism share in His death? Sharing in His death by our baptism, we were buried with Him so that as the Father’s glory raised Christ from the dead we too will live a new life” (Romans 6:3-4 AAT). Therefore, we have confidence to enter the Most Holy Place by the blood of Jesus (Heb 10:19). We have come “‘to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better message than Abel’s”(Heb 12:24). Jesus sanctified us by His own blood (Heb 13:12).
Jesus assured His followers they would be baptized with the Holy Spirit. After His death and resurrection, Jesus continued to preach the kingdom for forty days (Acts 1:3). Just before He ascended into heaven, Jesus told His disciples they would soon be baptized with the Holy Spirit “And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence” (Acts 1:4-5 KJV).
Then, Jesus ascended into heaven. “And when he had said these things, while they were looking, he was taken up, and went from their view into a cloud. And while they were looking up to heaven with great attention, two men came to them, in white clothing, And said, O men of Galilee, why are you looking up into heaven? This Jesus, who was taken from you into heaven, will come again, in the same way as you saw him go into heaven. Acts 4:9-11 BBE
On the day of Pentecost, they were baptized with the Holy Spirit. Up until that time, Jesus was the only one on earth who had been baptized with the Holy Spirit and thus was only one in the kingdom (Mt 11:11). Then the Father poured out the Holy Spirit on all flesh and brought the kingdom to us in the Spirit.
When the day of Pentecost was being celebrated, all of them were together in one place. Suddenly, a sound like the roar of a mighty windstorm came from heaven and filled the whole house where they were sitting. They saw tongues like flames of fire that separated, and one rested on each of them. All of them were filled with the Holy Spirit and began to speak in foreign languages as the Spirit gave them that ability. Acts 2:1-4 ISV
Men of Israel, listen to these words: Jesus the Nazarene, a man attested to you by God with miracles and wonders and signs which God performed through Him in your midst, just as you yourselves know— this Man, delivered over by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of godless men and put Him to death. But God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power. Acts 2:22-24 NASB
Brethren, I may confidently say to you regarding the patriarch David that he both died and was buried, and his tomb is with us to this day. And so, because he was a prophet and knew that GOD HAD SWORN TO HIM WITH AN OATH TO SEAT one OF HIS DESCENDANTS ON HIS THRONE, he looked ahead and spoke of the resurrection of the Christ, that HE WAS NEITHER ABANDONED TO HADES, NOR DID His flesh SUFFER DECAY. This Jesus God raised up again, to which we are all witnesses. Therefore having been exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He has poured forth this which you both see and hear.
For it was not David who ascended into heaven, but he himself says:
‘THE LORD SAID TO MY LORD,
“SIT AT MY RIGHT HAND,
UNTIL I MAKE YOUR ENEMIES A FOOTSTOOL FOR YOUR FEET.”’ (See Ps 16:8-11)
Therefore let all the house of Israel know for certain that God has made Him both Lord and Christ—this Jesus whom you crucified. Acts 2:29-36 NASB
Now Jesus sets at the right hand of His Father who is in heaven. He must reign until He has put all His enemies under His feet (1 Cor 15:20-28). Jesus will do away with the last enemy, death, at the resurrection (1 Cor 15:50).
Christ Jesus reigns as King by His Word and by the Holy Spirit in us
Jesus reigns over us if we love Him. If we do not love Him, He doesn’t. Just prior to His crucifixion, Jesus told His disciples and us He would as the Father to give us another Helper. (Other translations have Comforter, Advocate, Counselor, Paraclete for Helper). That helper is the Holy Spirit. Jesus explains the Holy Spirit’s role in His kingdom in what He told His disciples.
“If you love me, keep my commandments. I will ask the Father to give you another Helper, to be with you always. He is the Spirit of truth, whom the world cannot receive, because it neither sees him nor recognizes him. But you recognize him, because he lives with you and will be in you. I’m not going to forsake you like orphans. I will come back to you.
“In a little while the world will no longer see me, but you will see me. Because I live, you will live also. At that time, you’ll know that I am in my Father, that you are in me, and that I am in you. The person who has my commandments and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I, too, will love him and reveal myself to him.”
Judas (not Iscariot) asked him, “Lord, how is it that you are going to reveal yourself to us and not to the world?”
Jesus answered him, “If anyone loves me, he will keep my word. Then my Father will love him, and we will go to him and make our home within him. The one who doesn’t love me doesn’t keep my words. The words that you’re hearing me say are not mine, but come from the Father who sent me.
“I have told you this while I am still with you. But the Helper, the Holy Spirit, whom the Father will send in my name, will teach you all things and remind you of everything that I have told you. I’m leaving you at peace. I’m giving you my own peace. I’m not giving it to you as the world gives. So don’t let your hearts be troubled, and don’t be afraid. You have heard me tell you, ‘I’m going away, but I’m coming back to you.’ If you loved me, you would rejoice that I’m going to the Father, because the Father is greater than I am. I’ve told you this now, before I leave, so that when I do leave, you will believe. I won’t talk with you much longer, because the ruler of this world is coming. He has no power over me. But I’m doing what the Father has commanded me, to let the world know that I love the Father. Get up! Let us leave this place.” John 14:15-31 ISV
