No, I am not adding to Scripture. You are subtracting from Scripture. We are saved when we have faith. And faith is not a mental process. Faith is the visible evidence of our inner conviction. If you don't exhibit the evidence, then there is no inner conviction. Sure, you think the chair can hold your weight, but we don't know if you have faith in the chair until you put your butt in it with all your weight on it.
Sorry there is not such meaning for faith
Faith is trust - One believe and entrust onseself to the object of ones faithm
It is the faith, the surrender to God in baptism, that brings about salvation.
That is exactly my claim. If all you have is intellectual assent, then you don't really trust, you don't really believe, you don't receive salvation. But if you have faith, then you surrender to the one in whom you believe, and obey what He says do. He said if you surrender to baptism then you will be washed white as snow and have all blemished of sin removed. If you don't surrender to baptism then you don't really believe in Him.
Faith brings salvation not water
John 3:15 that whoever believes in him may have eternal life.
John 3:18 Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
John 3:36 Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
John 6:40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.”
John 6:47 Truly, truly, I say to you, whoever believes has eternal life.
John 11:25 Jesus said to her, “I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live,
John 20:31 but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
Acts 10:43 (ESV) — 43 To him all the prophets bear witness that everyone who believes in him receives forgiveness of sins through his name.”
Acts 13:39 (ESV) — 39 and by him everyone who believes is freed from everything from which you could not be freed by the law of Moses.
You cannot do miracles through the Holy Spirit without having Him with you. But like we see in the OT, the Holy Spirit was not indwelling them but only working through them. They did not receive the indwelling until they were baptized in water as we see commanded in Matt 28:19 and Mark 16:16.
There was no indwelling until Christ's glorification
John 7:38–39 (ESV) — 38 Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’ ” 39 Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
Nor were they baptised en the spirit
Cornelius and the gentiles were baptised en the Spirit had received the spirit and life all before water baptism
Absolutely all 120 received the miraculous gifts of the Spirit on Pentecost. The Apostles already had the indwelling; the rest may or may not have, we don't know. It appears that many more than just the Apostles were together when Jesus breathed on them and gave them the indwelling (John 20:19-20). No, Thomas was not with them, but it was not just the Apostles that were there.
It was more than the miraculous gifts it was the reception of the Spirit himself
Acts 10:47 (ESV) — 47 “Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?”
u
No one received the Holy Spirit's indwelling until Jesus was Glorified, and now we receive the indwelling of the Holy Spirit through water baptism, because that is the point at which we enter into union with Christ (Gal 3:26-27). We receive the indwelling when we have our sins cut from us (Col 2:11-14), and it is He who works in us to bring us new life and new union with God (Rom 6:4).
