4. JESUS CHRIST is both God and man, the 2nd person of the blessed Trinity (The Athanacian Creed)
Philippians 2:6-11
Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Proverbs 8:22-31
Rev 1:17 And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
Rev 1:18 I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
Colossians 1:15-19
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;
Titus 2:13-14
Looking for that blessed hope,
and the glorious appearing of the great God and our Saviour Jesus Christ;
Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
These are just a few scriptures that came to mind without opening up Bible studies; such as Naves, or Vines, etc.
Any good Bible study book would have ample scriptures testifying to the existence of Jesus and his work before his physical human birth.
John 8:56 Your father Abraham rejoiced to see my day: and he saw it, and was glad.
8:57 Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham?
8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
Jesus talking to Nicodemus in John chapter 3 - clearly claims that he had ascended and descended from Heaven.
