Verily, verily, I say unto you, He that believeth on me hath everlasting life.
(John 6:47)

That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
(Ephesians 3:17)

And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
(John 10:28-29)

And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.

There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. (Romans 8:1)

Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
(John 5:24)

He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
(John 3:18)

And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
(Ephesians 4:30)

Note: The day of redemption is the resurrection of the believers' bodies at Christ's coming.

For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
(1 Thessalonians 4:16-17)
