I have reserved to myself 144,000 who will not bow to the image

Joh 16:28 I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.

Joh 16:29 His disciples said unto him, Lo, now speakest thou plainly, and speakest no proverb.

I'd say that Christ truly came forth from the father and this isn't a proverb, but he was speaking plainly. One thing we need to understand here is that his words are true. Many don't believe it because they can't explain how it happened in this natural world.

Evolutionists normally use the same reasoning saying I can't believe in God because we can't explain him in the natural world. Well, that's just great isn't it. Let's ask them to explain the beginning of time. Was there a time before there was time? Get them to explain space. How far does it go? Where does it stop? And is there space beyond space? I mean where does it end.

The law of entripy proves this universe will have an end. It also proves this universe had a beginning. So therefore there is something greater than time. A dimension that has yet to be observed by the natural eye. Like Paul said "eye hath not seen" and also "I knew a man caught up to paradise, and heard unspeakable words which it is not lawful for a man to utter"(1 Cor 12:4). It's impossible to explain exactly when Christ was begotten, however we have God's word which tells us it happened in a time before creation or time.

Just because the natural eye can't observe or prove it, doesn't mean we can't believe it. Just because we can't observe or prove how time began doesn't mean we don't believe in time. It's here.

"As to when He was begotten, it is not for us to inquire, nor could our minds grasp it if we were told. The prophet Micah tells us all that we can know about it in these words, “But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall He come forth unto Me that is to be ruler in Israel; whose goings forth have been from of old, from the days of eternity.” Micah 5:2, margin. There was a time when Christ proceeded forth and came from God, from the bosom of the Father (John 8:42; 1:18), but that time was so far back in the days of eternity that to finite comprehension it is practically without beginning."(E. J. Waggoner, 1890, Christ and His Righteousness, pages 19-22)
