Of course it's relevant... If the letters of Paul are our first point of contact to the "christ" then how the next stories develop are just as important.
Do you realise that the stories of the Christ follow the letters of Paul by at least a generation?
How long is a generation, or two?
You do this purposely Thrud,
The first point of contact to Christ are the OT scriptures. (Christ made something very plain)
King James Bible
And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.You see the true point of contact for any believer is not Paul or the disciples and their writings.
It is the truth told through the Prophets. The truth about the Messiah and the New Covenant of Jeremiah.
The Prophets and people of the OT had this in common they knew God and the Prophets received the Holy Spirit.
We see the truth about Christ bring that same baptism that belief in Christ brings the baptism of the Holy Spirit.
The words of Christ and his teachings are what the OT teaches.
You do what so many atheists do. You believe the believers faith depends on the teachings of the written word in the NT and the disciples and Paul. But the truth is the believers faith depends on the words of the OT becoming a reality in the words of Christ in the NT.
Yes you do need to read it for context...
20 Our fathers worshipped in this mountain; and ye say, that in Jerusalem is the place where men ought to worship.
21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father.
22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
25 The woman saith unto him, I know that Messias cometh, which is called Christ: when he is come, he will tell us all things.
26 Jesus saith unto her, I that speak unto thee am he.It is by Spirit and truth we know God and Jesus Christ.
It is not reliant on scripture or written words. The power of the word is the Holy Spirit.
" My words are Spirit and they are life" Christ's testimony and the same taught in the OT that not by might nor power but by my Spirit.
So you are looking in the wrong place for the truth. You are looking at Paul and not at Christ.
Christs words should match the OT. And for the believe they do. But the truth is found in belief in Christ and the baptism of the Holy Spirit.
John 16:13 (KJV)
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
A living present day relationship with God through his Spirit.
What are you going to do now? Your search for truth is at an end. You now know you will never find the answers by examining Paul or anything he wrote. You will make no headway in Christianity now.
You cannot enter into the truth of Gods Spirit teaching you because you barred that way.
So what now? You alone get to choose.... Gods way or your own highway...
