You are approaching the gospels like eyewitness accounts
1 Many have undertaken to draw up an account of the things that have been fulfilled[
a] among us, 2 just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. 3 With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, Luke 1
For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were
eyewitnesses of his majesty. 2 Peter 1:16
As I've said before, there are two definitions of "Christian".
The Non-scriptural definition is anyone who says they are a "Christian" with some degree or another of claiming to believe in Jesus and his teachings as something or another, basically anyone as long as they claim to follow Jesus, whatever those words may mean to them.
The Scriptural definition is that Christians were first called such as the Disciples under Peter's authority in Antioch. Those would be Torah obedient Messianic Jews. Not Paul's specific brand necessarily, but Peter's.
Christians follow neither Peter or Paul, but Christ is the foundation of our faith. We trust in Christ's finished work on the cross to have saved us and he gets all the glory. Having trusted in Him, we have his power working in us mightily enabling us to keep a higher law of love, mercy, and grace.
This is a very important issue, what exactly does it mean to "believe on" Jesus? The word Pisteuon is more about being convinced and persuaded and having reason to believe something due to a logical and evidential reason, not "blind faith" which is somewhat more covered, though not entirely by Pistis.
It says that anyone who truly "believes on Jesus" will be saved, but it also says that anyone who "believes on Jesus" will be able to do miracles greater than the works he did.
So perhaps there's something to this "believe on" that actually means obeying his teachings and commandments, much to the common chagrin of "Christians" who insist otherwise.
The test to see who truly "believes on Jesus" should be those who are able to do works greater than the miracles described in the NT. If they can't, while claiming to "believe" in Jesus, then the text itself is calling them frauds. Jesus was quite clear that those who call him "Lord" while not doing the Will of the Father (the doers of "Lawlessness") will be rejected by him.
To believe in or on Christ is to rely on, cling to him and his finished work on the cross for our salvation. Being filthy sinners without any hope of saving ourselves, in due time Christ died for the ungodly, so whoever trusts him, that his death paid the penalty of their sins, is freely and wonderfully saved. The saved person then begins to grow in this grace, as a child of God and begins to learn obedience, not to get or stay staved, but because they are saved and Christ is living in and working through them so they begin to grow and trust and obey Him. The miracles greater than Christs? Why, leading others to salvation by leading them to trust in Christ for the matter. When Moses brought the ten commandments down, 3,000 people died. When the Holy Spirit came and ushered in the Age of Grace, or Church Age, 3,000 people gained eternal life on that very day. It was life and it was eternal, and it was free.
