They will know that there was a prophet among them. 

Ezekiel 33:31-33 

31 And they come unto thee as the people cometh, and they sit before thee as my people, and they hear thy words, but they will not do them: for with their mouth they shew much love, but their heart goeth after their covetousness.

32 And, lo, thou art unto them as a very lovely song of one that hath a pleasant voice, and can play well on an instrument: for they hear thy words, but they do them not.

33 And when this cometh to pass, (lo, it will come,) then shall they know that a prophet hath been among them.

John 20:19-29 

19 Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.

20 And when he had so said, he shewed unto them his hands and his side. Then were the disciples glad, when they saw the Lord.

21 Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you.

22 And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:

23 Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.

24 But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.

25 The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe.

26 And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.

27 Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.

28 And Thomas answered and said unto him, My Lord and my God.

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.

John 14:8-9 

8 Philip saith unto him, Lord, show us the Father, and it sufficeth us.

9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?

Jesus Christ the true God, created everything 

Colossians 1:15-19 

15 Who is the image of the invisible God, the firstborn of every creature:

16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:

17 And he is before all things, and by him all things consist.

18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.

19 For it pleased the Father that in him should all fulness dwell;
