yes witnessing is very important to determine truth and witnesses are essential, Jesus was witnessed by thousandths GOD Himself Yes, you forgot this also!!! and what you Sais diminished Jesus just like paul did.
In Jewish law, truth is confirmed by witnesses. Deuteronomy 19:15 says: “By the mouth of two or three witnesses the matter shall be established.” This principle was vital in their courts and in affirming any testimony. Even Jesus referred to this when He said, “If I bear witness of Myself, My witness is not true. There is another who bears witness of Me… the Father Himself, who sent Me, has testified of Me” (John 5:31, 37).
At Jesus’ baptism and transfiguration, the Father Himself was the witness, the Holy Spirit descended visibly, and people like John the Baptist and the disciples heard and saw it. This fulfilled the law’s requirement for multiple witnesses.
This matters because in Jewish tradition, no one could establish a teaching or authority without testimony. Jesus had the greatest possible witness: God Himself. This is why He said, “If anyone desires to do His will, he shall know concerning the doctrine, whether it is from God” (John 7:17).
Paul, by contrast, claimed to have seen Jesus in a private vision, saying, “Have I not seen Jesus Christ our Lord?” (1 Corinthians 9:1) and “Last of all He was seen by me also, as by one born out of due time” (1 Corinthians 15:8). His three accounts of the Damascus road event (Acts 9; 22; 26) differ, and those with him could not confirm what he saw or heard. Paul repeatedly insisted that his witness about himself was true: “I tell the truth in Christ, I am not lying, my conscience also bearing me witness in the Holy Spirit” (Romans 9:1), “The God and Father of our Lord Jesus Christ… knows that I am not lying” (2 Corinthians 11:31), and “Now concerning the things which I write to you, indeed, before God, I do not lie” (Galatians 1:20). He even said his gospel came “not from man, nor was I taught it, but… through the revelation of Jesus Christ” (Galatians 1:12).
By the law’s standard, and the words of Jesus, self-witness is not enough. Paul’s testimony rests entirely on his own claims, with no confirming witnesses, while Jesus was confirmed by the Father, the Spirit, and many human witnesses, fulfilling God’s requirement for truth.
Paul received his mystery gospel in secret with NO witnesses except his OWN self witnessing 3 times , therefore INVALID, INVALID, INVALID!
I suggest you go back and read again the words of Christ that you obviously have forgotten! you also do not know much about paul.
Much Much Much Love!
