There may be a mountain of evidence that the Bible is true, but there is only one proof of it: the baptism of the holy Ghost. That is what John the Baptist told Israel that the long-prophesied Messiah would do (Mt. 3:11; Mk. 1:8; Lk. 3:16). Therefore, whoever baptizes with the holy Ghost is the Messiah, the Savior of the world. Men can believe that Jesus is the Messiah, and believe it very deeply, (just as demons do – Jas. 2:19), but that is all we can do without help from God. Without the holy Ghost, no one can say (and know for certain it is true) that Jesus is Lord (1Cor. 12:3).
We can be so devoted to belief in Jesus that we give up our lives for it, but that self-sacrifice will mean nothing to God unless it was motivated by the love of God, which enters our hearts only by the holy Ghost (1Cor. 13:1–3; Rom. 5:5). We need the holy Ghost baptism because Jesus said we must be born again (Jn. 3:3, 7), and the baptism of the holy Ghost is the way to enter, or be born into, God’s family (cp. 1Cor. 12:13; Rom. 6:3; Gal. 3:27). We need to hear about Jesus because the Father gives the holy Ghost only to those who believe in Jesus and come to Him in Jesus’ name (Jn. 14:26). Though we pray to God in the name of Muhammed from now until doomsday, He will not give us the Spirit because the Spirit comes only in Jesus’ name.
So, don’t get too excited about historical evidence concerning the scriptures and the Messiah they proclaim, whether it be archaeological or documentary evidence. God’s living proof of His Son is infinitely more exciting. An empty tomb is evidence, but it does not prove that Jesus rose from the dead; only the holy Ghost does that. “The Spirit is the witness”, John wrote, “because the Spirit is truth” (1Jn. 5:6). Historical evidence can be interesting, but its value pales to worthlessness in comparison to God’s living testimony of His Son. That baptism is not like a dusty potsherd, known by and useful to men long ago, but not now. No, God has never stopped offering His unique proof that Jesus is Savior and Lord; in every generation since Jesus suffered and died, God has been baptizing with the Spirit humble souls who obey Him (cp. Acts 5:32).
