I would say that eternal is indeed eternal but in this present world were are birthed into a ‘lively hope’ of eternal life.
1Pe 1:3 ¶ Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
There is nothing to worry about period IF we remain faithful to the Lord unto the end. He has promised the strength to accomplish the ends of hope, life eternal. We must simply walk in obedience and trust in the Lord.
He has begotten us again (born again) to a lively hope ( a new life in Christ) by the resurrection in Jesus Christ (a past event--the gospel).
There are no "ifs!
Eternal life, the gift of salvation (Romans 6:23) is unconditional.
I give unto you eternal life. That is what the verse says.
If one must keep conditions to maintain it then the verse would not be true and Christ Himself would be a liar, for he says the same thing in John 10:27-30
"I give unto them eternal life."
"They shall never perish."
"No man shall pluck them out of my Father's hand."
These are absolute statements regarding eternal life. If we don't have eternal life right now then Christ is a liar.
If we should lose eternal life at any time then eternal would become temporary, and Christ would be a liar. Eternal means eternal and can never become temporal. The very definition of eternal means you cannot lose your salvation. Otherwise eternal does not mean eternal and Christ is found to be a liar. By believing one can lose their salvation, it is an attack on the integrity of Christ.
NE that seeks after God NO NOT ONE".
