What was Jesus before becoming a man?
Your assumption as well as the billions of people assumption was he was a God?
That happens when people don't use the Bible and take their answers on the assumption of others.
Again, what was Jesus before becoming a man?
John 5:38-40 Easy-to-Read Version (ERV)
38 The Father’s teaching does not live in you, because you don’t believe in the one the Father sent. 39 You carefully study the Scriptures. You think that they give you eternal life.
These same Scriptures tell about me! 40 But you refuse to come to me to have that life.
Jesus was the prophecies that came true
Jesus was in the mind of God even before the world was created
1 Peter 1:20 Expanded Bible (EXB)
20 Christ was ·chosen [destined; L foreknown] before ·the world was made [L the foundation/creation of the world], but he was ·shown to the world [revealed] in these last times for your sake.
Who chose Christ before the world was made?
Who destined Christ before the world was made?
Who foreknown Christ before the world was made?
God chose Christ before the world was made
Hence Christ isn't God who made the choosing.
Jesus Christ is the firstborn of all creation
And as such he is not God but the first born of all creation.
Is that found in the Bible?
You betcha.
Colossians 1:15 New International Version (NIV)
15 The Son is the image of the invisible God, the firstborn over all creation.
If he is the firstborn over all creation then he is the reason why all creation exists.
He was created first by God Almighty and as being created, Jesus Christ is not the creator.
Now going back to who are the ANTICHRIST
2 John 7 New King James Version (NKJV)
7 For many deceivers have gone out into the world
who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist.
in another translation the same verse is written like this:
2 John 7 The Message (MSG)
7 There are a lot of smooth-talking charlatans loose in the world who refuse to believe that Jesus Christ was truly human, a flesh-and-blood human being. Give them their true title: Deceiver! Antichrist!
So if a person, people or an organization refuse to believe
that Jesus Christ was truly human, a flesh-and-blood human being
Then the Bible says they are deceivers and antichrist
And we all know that such persons do not have eternal life.
Now how can we regain eternal life before everything ends?
Remove yourself from such antichrist doctrine and follow the right teachings of Jesus Christ
John 17:1-3 New King James Version (NKJV)
Jesus spoke these words, lifted up His eyes to heaven, and said: “Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him.
And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
