Haven't seen any scripture that implies that Jesus, having risen from the dead, now knows the time that He will return. Either way, I'm Ok with it.
Didn't he tell John?
Rev 11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
Rev 11:11 And after three days and an half the Spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them.
Rev 11:12 And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.
Rev 11:13 And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
Rev 11:14 The second woe is past; and, behold, the third woe cometh quickly.
Rev 11:15
And the seventh angel sounded; and there were great voices in heaven, saying,
The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
Rev 11:16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
Rev 11:17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
Rev 11:18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged,
and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
Rev 11:19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
The 7th trump is the second coming and here Jesus has shown John that when the two prophets are killed, 3.5 days later is the second coming. We could even go to the start of the 42 months and the appearance of the beast to know there is 42 months until that 7th trump second coming.
I believe Christ knew nothing of this when he walked the Earth which is why he didn't speak of 42 months, the deaths of the two prophets and the 3.5 days being dead before they raised from the dead and the same hour the 7th trump sounded. Those things only come from Christ after he ascended which is pretty solid evidence he does now know the time of his coming.
