Before you can define Christ, you after to know who Jesus is, the only begotten Son of God.
Christ is the seed of Abraham, the fulfillment of God's promise and oath to him.
The Son of God was the Son of God before the foundation of the world. Before He took on flesh.
Before He took on the seed of Abraham.
agreed and looking back upon all Scripture which Peter did not have since the N.T. was not written we now know the following that the disciples did not understand until Jesus had opened their minds and hearts to understand after His Resurrection concerning everything written about Him in the scriptures- in the Law, Psalms, Prophets.
Luke 24:25-27
25 And He said to them, "O foolish men and slow of heart to believe in all that the prophets have spoken!
26 " Was it not necessary for the Christ to suffer these things and to enter into His glory?"
27 Then beginning with
Moses and with
all the prophets, He explained to them
the things concerning Himself in all the Scriptures.
Luke 24:44-45
44Now He said to them, "These are My words which I spoke to you while I was still with you, that
all things which are written about Me in
the Law of Moses and
the Prophets and
the Psalms must be fulfilled."
45 Then He opened their minds to understand the Scriptures,
Jesus said the Holy Spirit will bear witness of HIM
John 15:26
“When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—
he will testify about me. 27 And you also must testify, for you have been with me from the beginning.
John 16:13-14
But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
14 He will glorify me because it is from me that he will receive what he will make known to you.
Jesus identity as God(YHWH) below in the N.T. And there are several passage I'm leaving out where it is YHWH in the OT passage quoted in the N.T. and applied to Christ identifying Him as YHWH. One example is Romans 10:13; Joel 2:32- calling on the name of YHWH (LORD) to be saved.
John 8:24
I told you that you would die in your sins. Yes, if you don't believe that
I AM(YHWH), you will die in your sins."
John 8:58
Jesus said to them, "Truly, truly, I say to you, before Abraham was born,
I Am.(
YHWH)"
John 1:1
In the beginning was the Word, and the Word was with God, and
the Word was God.
John 20:28
Thomas answered and said to Him, "My Lord and
my God!"
Romans 9:5
Theirs are the patriarchs, and from them is traced the human ancestry of
Christ who is God over all forever praised! Amen.
Titus 2:13
looking for the blessed hope and the appearing of the glory
of our great God and Savior Christ Jesus
1 Timothy 3:16
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.
Hebrews 1:8
But of
the Son He says,
"
YOUR THRONE O GOD IS FOREVER AND EVER
Hebrews 1:10
He also says,
"In the beginning,
O Lord, you laid the foundations of the earth,
and the heavens are the work of your hands.
2 Peter 1:1
Simon Peter a servant and apostle of Jesus Christ
To those who through the righteousness of
our God and Savior Jesus Christ have received a faith as precious as ours
1 John 5:20
We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true even in His Son
Jesus Christ. He is the true God and eternal life.
These passages in Revelation make it clear that Jesus is God. Remember it is Jesus in the NT who is Coming back to earth that every eye will see. It was Jesus who was pierced on the cross for our sins. John is clearly once again calling Jesus God/ YHWH.The Coming and the coming in the clouds refers to Jesus.
Isaiah 48:12
"Listen to Me, O Jacob, even Israel whom I called;
I am He, I am the first, I am also the last.
Revelation 1:7-8
7 BEHOLD,
HE IS COMING WITH THE CLOUDS,
and every eye will see Him, even
those who pierced Him; and all the tribes of the earth will mourn over Him. So it is to be. Amen.
8 "
I Am the Alpha and the Omega,"
says the Lord God, "who is and who was and who is to come, the Almighty."
We know from Revelation 1:8 that
Alpha and Omega is the
Almighty. So we can see that Christ is the Almighty
Revelation 1:17
17And 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:
We know from
Revelation 1:17-18 that the
first and the last is He that liveth, was dead, but is alive forevermore is Christ.
Revelation 22:12-13
12 "Behold,
I Am coming quickly, and My reward is with Me, to render to every man according to what he has done. 13 "
I Am the Alpha and the Omega,
the first and the last, the beginning and the end."
We know from Revelation 22:13 that the
first and the last is the
Alpha and Omega.
Revelation 22:16,20
16 "
I, Jesus, have sent My angel to testify to you these things for the churches. I am the root and the descendant of David, the bright morning star."
20 He who testifies to these things says, "
Yes, I Am coming quickly." Amen.
Come, Lord Jesus.
So we now have an advantage in that we can examine both Testaments and see what the OT prophets wrote, what Jesus said and taught and what the Apostles had written about Jesus identity after Pentecost when they wrote scripture a few years later. They understood as Jesus had promised once they received the Holy Spirit that He would bring those things to their remembrance and would understand them at that time.
hope this helps !!!
