Just a second...
"But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship Him." (John 4:23)
Interesting. Can't have that verse without its companion: "God is a Spirit: and they that worship Him must worship Him in spirit and in truth."
The word translated "hour" refers to any and everything from hour (as in sixty minutes) to a season. In other words, the time is now now.
The fourth dimension
Time is precious. The more of it goes by, the more you realize how little you utilize and subsequently, how little you have left. I'm actually talking to myself. Moses prays in Psalm 90 (verse 12) to "teach us to number our days, that we may apply our hearts unto wisdom." David prays in Psalm 39 (verse 4) "to know...the measure of my days, what it is; that I may know how frail I am." We are limited by time, by the fourth dimension. Nothing to be concerned about or afraid, no. Just circumspect. If you believe God made you and put you here for a season (this one) and a purpose, it should follow that there are times (if not all of it) where He has scripted you down to the millisecond. To where each thought, each action, each notion and moment is meant to be. But it takes time to learn to walk in this. And trust me, if you go around thinking about it and wanting it more than simply enjoying the Lord for His sake, it will drive you crazy. Tick-tock, tick-tock, tick-tock. You get the idea. It's not something you can control.
Moses, arguably one of the humblest and meekest people in the Bible, prays to fill the days and hours with God's wisdom. David takes an even more low-key tone in desiring to know his frailty. We truly are fragile. James says (4:15) "For what is your life? It is even a vapour, that appeareth for a little time, and vanishes away." Making the most, then, of the time we been blessed with and gifted is the order of the day. The best way to do that, I'd say, is to simply press in to knowing and loving God to the best of our ability.
That's "every hour" in Latin. When Jesus spoke of "the hour coming", He's talking about a transition to a simpler, yet more powerful way of walking with our Heavenly Father. Something that He had to not only initiate--as in herald--but He also had to show us how it's done. And this is why He says "the hour cometh, and now is". As an aside, I'm skeptical of anything that seeks to shed light on what was going on between the age of twelve and of thirty, in the life of Jesus. Not because I'm not willing to accept new information, but because our time and life before the Lord is a holy thing. The practices and procedures that Jesus developed--and subsequently walked in, while certainly based on the Law of Moses (as Jesus was Jewish), would have been necessarily made His own during that time. It's almost like it's none of our business beyond a certain point. And so rewinding back to that desire we all have to "walk in the Spirit" (Galatians 5:16) every moment and every hour perfectly, i.e. "to walk, even as He walked" (1 John 2:6): Lay it down. Don't worry about it.
The fourth wall
That imaginary barrier through which the actor looks at the audience. Here's the thing about time and life and everything else: God is your audience. And because of what Jesus did (everything) while here for a short thirty-three years, you are able to look at Him. God dwells without time, as in outside it. It's not hard to wrap your mind around. Instead of time, it's more of a passage of moments in Heaven. So look at God because He's always looking at you. And the more you do this in whatever way you choose--in love, the more life will transition from a harried and hurried passage of seconds and minutes and hours, to a passage of moments. Each one more infused with the presence of God than the last.
