Sinners who are given eternal life by Jesus Christ don't become God. Jesus said:
(Joh 10:27 NKJV) My sheep hear My voice, and I know them, and they follow Me.
(Joh 10:28) And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
(Joh 10:29) My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand.
He doesn't say (in John 10 or anywhere else) that His sheep become God. In John 17 He says:
(Joh 17:1) 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,
(Joh 17:2) as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him.
(Joh 17:3) And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
Yes, eternal life involves knowing God, and knowing Jesus Christ, but not being God.
We have eternal life IN God.
We now have everlasting life in our own experience as a child of God.
In the future God, being outside of time (eternal) if He wishes can cause us to time travel to different times in history to witness to events as they actually took place. God is not limited by time. We are. In God, we will have access to what His Life sees as He shares from his omniscience with us.
That is why and how we can gain more eternal life by being a believer who pleases God in doing His will now.
Not everyone will receive the same eternal rewards. We all have eternal life by default when living with God forever.
He is eternal life!
Not all who have been given eternal life (believers) will inherit from God sharing in His eternal life with them. (rewards)
That sharing in His eternal life will be rewards from God to the faithful believer to grow in grace and knowledge.
Here it is...
For no one can lay any foundation other than the one already laid, which is Jesus
Christ. If anyone builds on this foundation using gold, silver, costly stones, wood,
hay or straw, their work will be shown for what it is, because the Day will bring it
to light. It will be revealed with fire, and the fire will test the quality of each person’s
work. If what has been built survives, the builder will receive a reward. If it is burned
up, the builder will suffer loss but yet will be saved—even though only as one escaping
through the flames. 1 Cor 3:11-15
Those who based their walk upon false doctrines will have wood, hay, or straw. Their works will be burned up.
They will not have access to eternal rewards we could have in God. They are saved forever for having initially believed in Christ.
All their works will be burned up. Yet, will be saved as a man is saved running from a burning house.
If it is burned up, the builder will suffer loss but yet will be saved—even though only as one
escaping through the flames.
I pray for those who have ears to hear they will understand what I just said.
In Christ, GeneZ
