I see that you believe in the water baptism and the necessity of that being the remission of the sins that are forgiven. I note that in the Book of Acts, and God showed me this at 16 years old, that the apostles always baptized in the name of Jesus. The power of heaven and earth is in the name of Jesus, is this the correct way? Jesus said, I am with you and I will be in you. He said this because he was with them but he was taken up and he would send the Comforter, the Holy Spirit, the same Holy Spirit that was inside Him to be in us. I believe that this is the event of the Baptism of the Holy Ghost, which those who believe should receive. The baptism in the book of Acts seems to be very important to the apostles, using the name of Jesus instead of titles of Jesus, Father, Son and Holy Ghost, which are actually titles of the diety of Christ. If you have Jesus, you have the Father and the Holy Ghost. It is one Spirit. I talk with pastors and they always say, God is three in One. I ask, three in one what?, I believe they are three manifestations of the same one Spirit. Is this correct in your eyes?
Answer:Regarding baptism in the name of Jesus, see:
Should baptism be done only in Jesus' name?
In whose name are we to be baptized?
Regarding the baptism of the Holy Spirit:
You are inconsistent in your application. The baptism of the Holy Spirit is something the Spirit chose to do to a person. There are only two mentions of it happening: Acts 2 and Acts 10. The baptism practiced by the early church is easily shown to be water baptism, something a person chose to have done. See The New Birth of Water
Besides, the Scriptures teach that today there is only one baptism. "There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all" (Ephesians 4:4-6).
Which then brings us to your third point that there is only Jesus. The passage above lists seven unique things. Those seven things are not seven manifestations of one thing. They are each unique. You agree that there is one Lord, but Paul says there is also one Spirit and one God and Father. This is just one of many verses which show that God is three beings perfect united in one cause. See Do You Believe in Three Gods or One?, Is the Holy Spirit Jesus? and Was the spirit of Christ the Holy Spirit?
