Jesus was very clear to Thomas. SPirit, and God is a SPirit mind you, doesnt come with observation as you see me as a man, see Jesus in Luke 17:20-21. You dont have a clue what was being conveyed to Thomas, and what Thomas finally saw.But you do deny the bodily resurrection of Christ, which even Jesus Himself proclaims, when He showed His wounds to Thomas.
Nice to know that you even call Jesus a liar.
When I saw Him as He really and became like Him as well, 1 John 3, I said the same thing Thomas did, My Lord and my God how I have missed you all along being deceived by the teachings of man that a man is a god. Jesus came to this same realization in Matt 3:16, you can read it how it was opened to him just as it was opened to Thomas and 120, and Moses and Adam and Abraham and me and all who has received form God the very same SPirit. God really is a SPirit you just dont believe Him that He is and cling to the creeds of man who worship a god of flesh instead of SPirit.
