First of all, there’s absolutely no evidence for his claims whatsoever. Jesus’ miracles and ultimately his resurrection were witnessed by hundreds and hundreds of people. The Gospel writers, specifically Luke, refer to these eyewitness multiple times. “Don’t take my word for it, ask the eyewitnesses who are still living, who saw Christ after his resurrection, etc. etc.” Perhaps the most compelling argument is the tenacity of the martyrs of the early church. If Christ was a lie, why would so many willfully go to their deaths for the cause?
"29": Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
"30": And many other signs truly did Jesus in the presence of his disciples, which are not written in this book:
"31": But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
II Peter 1:
"16": For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.
"17": For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
"18": And this voice which came from heaven we heard, when we were with him in the holy mount.
"19": We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
"20": Knowing this first, that no prophecy of the scripture is of any private interpretation.
"21": For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
