Is Jesus like Enoch and Elijah, no more?
Genesis 5:24
Yes you are picking up to allusions in the Torah to the future and these are allusions in Quran repeated to prepare for the Mahdi (a). There also so much to be said about Elijah (a) and Jesus (a) relationship. Elijah came back and was witnessed by people, then when hiding, and one of the proofs that Jesus used to show that he came back, was to say there was someone like him before (John (a)) and so he is saying, if I am here, he has to come back for this reason, because I'm leaving you to come back, but in the mean time, there is always one with the position of the holy spirit or word of light of God in the world, whether hidden or apparent. This is why he appeals to the holy spirit reality and that in the mean time while they wait for the comforter to come (Mohammad (s)), they will be comforted by the holy spirit and he will send him when he leaves, this means, Elijah (a) takes the place of Jesus (a) till Mohammad (s).
And then we have the mysterious Khidr (a) in Quran doing license to kill stuff on behalf of God.
There is a always a spirit from God on earth channeling light, but, what happens is all religions acknowledge the light but take from it what suits their desires and abandon of it what they like, and oppose the current place holder of it.
If we recognize the guiding king in form of light, all truth would become apparent to us, and we would recognize the light walking among humans as well.
