John 1: 33
He upon whom you see the Spirit descending and remaining upon Him, this is the one who baptizes in the Holy Spirit.
In the Old Testament the Holy Spirit would come “on” someone and that person would perform anointed works. Gideon blew his horn; many prophesied. But the Holy Spirit would lift off them after their task was accomplished. He did not come upon them and remain. The time of the Holy Spirit was not yet.
John the Baptist baptized in water but announced that one was coming after him who would baptize in the Holy Spirit (Matt. 3: 11, Mark 1: 8, Luke 3: 16, John 1: 33). He spoke, of course, of Jesus. When Jesus ascended to heaven, He sent the Holy Spirit to be with us, to live with us forever as we saw in John 14: 16. No longer was the Holy Spirit to come “on” us and then vacate. Instead Jesus said that He was going to send the Holy Spirit to be with us forever to be our constant helper, teacher and guide. So now the Holy Spirit has come and made His abode with us. Paul wrote to the church at Corinth, “Do you not know that you are a temple of God, and that the Spirit of God dwells in you?” (1 Corinthians 3: 16). Then in Romans 8, the eleventh verse Paul wrote, “He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who indwells you.” Now we have the Holy Spirit with us, dwelling in us all of the time rather than coming upon us in a time of need. He is here to be your constant standby and He couldn’t do that very well if He had to come and go. So, Jesus sent Him into the world to be with us and to stay with us until Jesus comes back to establish His Kingdom in the earth. We are never abandoned because God has made provision for us to have a divine helper with us at all times.
