Passing up This life is just beginning. Take for instance this notion that, somehow, all our free moments are to be somehow saved and stored for some indeterminate time in the (hopefully) near future and enjoyed, then. Call it your "weekend" or perhaps maybe a vacation. You will get that respite. But again, if you don't see it now--or at least know that it's available to you right now, you most likely may not experience the joy and "times of refreshing" (Acts 3:19) that those times indeed were guaranteed to provide. God wants to give them, but He's already made it possible to have that peace, His peace, wherever and whenever you find yourself.
"For He is our peace..." (Ephesians 2:14)
"And came and preached peace to you which were afar off, and to them that were nigh. For through Him we both have access by one Spirit unto the Father." (Ephesians 2:18)
We're on our way. Again, this life is literally just beginning. We're on our way to see Jesus and the Father face to face. The time it takes to work out our quirks and peccadilloes on the way there is but a small portion of its intended use. But time is a gift. And as we endeavor to get close as possible to God now, the more time will stand still. Know that God sees you now, right now, as He sees His Son. We have the same heart. It's our mind that may or may not be in tune with His. This is easily remedied. Because, as He has given us His peace to draw upon right now--presently, we also have the very mind of Christ. And it's either true or it isn't.
"For who hath known the mind of the Lord, that he may instruct Him? But we have the mind of Christ." (1 Corinthians 2:16, emphasis mine)
Passing a stone
"Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; And are built upon the foundation of the apostles and prophets, Jesus Christ Himself being the chief corner stone;" (Ephesians 2:19-20)
An uncle of mine has an oft-used adage. My generation-specific ethos is nearly loath to requote it. I'm also hesitant as I am a stickler for catch-phrase originality. However, some statements are irreducible in their practicality and truth and so here goes: "One of our primary aims before getting to Heaven is to take as many people with us before we get there." That's pretty much verbatim and I don't think he'd mind me plagiarizing. I say all that to say that it's true. The whole of our life is a testimony and a ministry. A wide-scale vocalization on the part of God in whatever ways you're made up to witness. Don't be shy. I used to worry about witnessing in public. But as I got to know the Lord, I found both confidence and peace in those areas and arenas but I also came to the realization that, once someone knows you're a believer (an "Evangelical", as it were...) they'll be watching everything you do anyway.
"In whom all the building fitly framed together groweth unto an holy temple in the Lord: In whom ye also are builded together for an habitation of God through the Spirit." (Ephesians 2:21-22)
God is doing things on a scale that we'd barely believe. But we're part of it. You're just as much a part of it as I and the more we endeavor to be one another's servant in the things of Christ (any- and everything), the quicker it'll happen--whatever it may be. Personally, I feel that it's not that life is so short, just that it's so important.
"But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none; And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not; And they that use this world, as not abusing it: for the fashion of this world passeth away." (1 Corinthians 7:29-31)
