Since according to the Gospel of John[20:30]

[Mary Naeem]

Since according to the Gospel of John[20:30] it was impossible to narrate all of the miracles performed by Jesus, the Catholic Encyclopedia states that the miracles presented in the Gospels were selected for a twofold reason: first for the manifestation of God's glory, and then for their evidential value. Jesus referred to his "works" as evidences of his mission and his divinity, and in John 5:36 he declared that his miracles have greater evidential value than the testimony of John the Baptist.
