For there are not three persons in that Godhead but ONE. Thus we are NOT born again by the Spirit of Life of Jesus coming in, and then subsequent to that the Holy Spirit coming in to give us power. If that were true, why are we dishonoring the Father by not giving Him a part in our complete salvation, for if salvation is of the Lord and there are three Lords, then HE (Father) must have something to do, too. But surely it can be seen that Jesus made this very clear that it was He and He alone Who is God and it is He and He alone Who is coming into the believer.
John 14:16 says that the Father will send another Comforter.
But verse 17 says that He (Jesus) dwelleth with them and should be IN them later.
In verse 18 He says He will come to them.
In verse 23 in speaking to the disciples He said, “We (Father and Son) will come unto him.” Thus it is the Father, Son and Holy Ghost all coming in at the one time for IT IS ONE PERSON comprising the Godhead. That advent took place at Pentecost. There aren’t two comings of the Spirit, just one. The trouble is that people don’t know the real truth, and they simply believe in Jesus for remission of sin but never go on to receive the Spirit.
