And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.

People's New Testament

10:28 I give unto them eternal life. To his sheep. Eternal life means not eternal existence, but eternal bliss. God hath made the soul deathless, but it may exist in banishment from heaven.

Wesley's Notes

10:27-29 My sheep hear my voice, and I know them, and they follow me, and c. - Our Lord still alludes to the discourse he had before this festival. As if he had said, My sheep are they who, Hear my voice by faith; Are known (that is, approved) by me, as loving me; and Follow me, keep my commandments, with a believing, loving heart. And to those who, Truly believe (observe three promises annexed to three conditions) I give eternal life. He does not say, I will, but I give. For he that believeth hath everlasting life. Those whom, I know truly to love me, shall never perish, provided they abide in my love. Those who follow me, neither men nor devils can pluck out of my hand. My Father who hath, by an unchangeable decree, given me all that believe, love, and obey, is greater than all in heaven or earth, and none is able to pluck them out of his hand.

Margin never

Or, in no wise ever perish. Cf. Jn 6:37.

Jamieson-Fausset-Brown Bible Commentary

28. I give unto them eternal life-not "will give them"; for it is a present gift. (See on [1822]Joh 3:36; [1823]Joh 5:24). It is a very grand utterance, couched in the language of majestic authority.

Matthew Henry's Concise Commentary

10:22-30 All who have any thing to say to Christ, may find him in the temple. Christ would make us to believe; we make ourselves doubt. The Jews understood his meaning, but could not form his words into a full charge against him. He described the gracious disposition and happy state of his sheep; they heard and believed his word, followed him as his faithful disciples, and none of them should perish; for the Son and the Father were one. Thus he was able to defend his sheep against all their enemies, which proves that he claimed Divine power and perfection equally with the Father.
