I replied, "I believe He does indeed exist".
He responded, "Do you have any evidence to prove that God exists?"
"Yes. Jesus.", I answered.
When someone claims to have a supernatural vision of, for example, Our Lady, the Church does not say that it believes that Our Lady is appearing, but instead that it believes the person who claims that they have had a vision is telling the truth. The individual goes through a rigorous examination to see if they are a person of honesty, credibility, truthfulness, and of sound mind and spirit.
So how do we know that Jesus is the Son of God? A good place to begin is to study the testimony of the witnesses. The disciples witnessed Jesus perform miracles, they witnessed Him calming the sea, they witnessed Him on Mount Tabor with Moses and Elijah, and heard the voice of God say "This is my Son, the beloved, listen to Him". And above all St. John the Evangelist tells us:
"But when they came to Jesus and found that he was already dead, they did not break his legs.A closer look at the word 'true' reveals:
But one of the soldiers pierced his side with a spear, and at once there came out blood and water.
And he who saw it, has given testimony, and his testimony is true. And he knows that he what he says is true; that you also may believe."
True (ἀληθινὴ)Three days after his death, Jesus appeared to Mary Magdalen and the other disciples. What Jesus said came true. And on the third day......
Genuine, according to the true ideal of what testimony should be.
Literally, true things. As distinguished from false. Thus, by the use of the two words for true, there are brought out, as Westcott remarks, the two conditions which testimony ought to satisfy; the first, that he who gives it should be competent to speak with authority; and the second, that the account of his experience should be exact."
Yes, I believe God does indeed exist.
