The Critical and Exegetical Hand-book to the Gospel of John, of 1884, by H. A. W. Meyer, Th.D., page 183, says on John 5:24:
“Verse 24. . . . The [making alive] is accomplished in him, he has eternal life (3:15), that is, the highest spiritual life, which, upon his entrance into the Messiah’s kingdom, reaches its consummation in glorious Messianic [life]. He has, in that he is become a believer, passed from spiritual death . . . into eternal life (the life par excellence), and cometh not into (condemnatory, compare 3:18) judgment, because he has already attained unto that life. The result of this is: [death he will by no means see], 8:51. On the perfect [he has passed over] see 3:18; 1 John 3:14.”
