Without a doubt, Jesus Christ is God

John 1:1-3 

1 In the beginning was the Word, and the Word was with God, and the Word was God.

2 The same was in the beginning with God.

3 All things were made by him; and without him was not any thing made that was made.

Isaiah 43:3-15 

3 For I am the Lord thy God, the Holy One of Israel, thy Saviour: I gave Egypt for thy ransom, Ethiopia and Seba for thee.

4 Since thou wast precious in my sight, thou hast been honourable, and I have loved thee: therefore will I give men for thee, and people for thy life.

5 Fear not: for I am with thee: I will bring thy seed from the east, and gather thee from the west;

6 I will say to the north, Give up; and to the south, Keep not back: bring my sons from far, and my daughters from the ends of the earth;

7 Even every one that is called by my name: for I have created him for my glory, I have formed him; yea, I have made him.

8 Bring forth the blind people that have eyes, and the deaf that have ears.

9 Let all the nations be gathered together, and let the people be assembled: who among them can declare this, and shew us former things? let them bring forth their witnesses, that they may be justified: or let them hear, and say, It is truth.

10 Ye are my witnesses, saith the Lord, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.

11 I, even I, am the Lord; and beside me there is no saviour.

12 I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the Lord, that I am God.

13 Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?

14 Thus saith the Lord, your redeemer, the Holy One of Israel; For your sake I have sent to Babylon, and have brought down all their nobles, and the Chaldeans, whose cry is in the ships.

15 I am the Lord, your Holy One, the creator of Israel, your King.

16 And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.

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:
