John 5:36
But the testimony which I have is greater than the testimony of John; for the works which the Father has given Me to accomplish–the very works that I do–testify about Me, that the Father has sent Me.
John 9:1-7
As He passed by, He saw a man blind from birth. 2 And His disciples asked Him, “Rabbi, who sinned, this man or his parents, that he would be born blind?” 3 Jesus answered, “It was neither that this man sinned, nor his parents; but it was so that the works of God might be displayed in him.4 We must work the works of Him who sent Me as long as it is day; night is coming when no one can work. 5 While I am in the world, I am the Light of the world.” 6 When He had said this, He spat on the ground, and made clay of the spittle, and applied the clay to his eyes, 7 and said to him, “Go, wash in the pool of Siloam” (which is translated, Sent). So he went away and washed, and came back seeing.
John 10:37-38
If I do not do the works of My Father, do not believe Me; 38 but if I do them, though you do not believe Me, believe the works, so that you may know and understand that the Father is in Me, and I in the Father.”
Matthew 12:38-40
Then some of the scribes and Pharisees said to Him, “Teacher, we want to see a sign from You.” 39 But He answered and said to them, “An evil and adulterous generation craves for a sign; and yet no sign will be given to it but the sign of Jonah the prophet; 40 for just as JONAH WAS THREE DAYS AND THREE NIGHTS IN THE BELLY OF THE SEA MONSTER, so will the Son of Man be three days and three nights in the heart of the earth.
Matthew 17:22-23
And while they were gathering together in Galilee, Jesus said to them, “The Son of Man is going to be delivered into the hands of men; 23 and they will kill Him, and He will be raised on the third day.” And they were deeply grieved.
