To put Heaven into perspective the best I can, I am going to provide an excerpt that I previously wrote about the power of God:
"If [God] indeed showed himself in a more definitive manner, or according to our visual awareness (e.g. waving from the clouds on a golden sleigh, giant hands lifting mountains, etc.), a power so far beyond the universe suddenly interjecting the universe would demolish all in the vicinity [Richard Deem; God and Science]. This is justified by the very words of God, in Exodus 33:20, saying, 'You cannot see my face, for no man can see me and live.'According to the given premises, all will be invigorated with enhanced entities capable of enduring the full presence of God. Additionally, when understanding that we are assimilated to an earth incapable of exhibiting the full presence of God, we then reveal further evidence that any place capable of exhibiting such must be physically incomprehensible from the current conception. As Richard Deem writes, '"Since Heaven is where God lives, it must contain more physical and temporal dimensions than those found in this physical universe that God created. We cannot imagine, nor can we experience in our current bodies, what these extra dimensions might be like."
Simple examples tend to put seemingly great complexities into perspective. Imagine the power of a star resting billions of miles away. The light shines so brightly, it can still be seen regardless of its distance, but it is days old by the time it reaches our eyes. We know that human vision is harmed when staring into the closest star of all, the sun. The creator of substances as powerful as these must have a natural light far beyond any of the creation, including the power of the stars, therefore it is for our own good that we cannot see God in full form."
I realize that to many skeptics an eternity in Heaven, or an eternity anywhere for that matter, is also completely illogical. Yet one has to acknowledge that time is a property of this universe - it can be described as a system used to measure change and sequentiality. If it indeed exists, it is not congruent with this universe in the sense that it and other spiritual dimensions are not timed, rather they are eternal because they are not physical properties of this universe. In the current conception one cannot comprehend the true concept of eternity when both mentally and physically accustomed to one's own system of existence. The thought of eternity is the fabrication of trillions of years, yet when the final year is reached, trillions more are added. That is precisely a finite interpretation, thus infinity is seemingly an illogical concept. Ultimately, it is not complete absurdity when rationally considering concepts beyond the universe.
Question: "I love my wife, is there still marriage in Heaven?"
I would rather not thoroughly answer that question for 2 reasons: I am not married yet nor have I been to Heaven. In my opinion, it would not be fair if I did with absolute assurance, and would appear as if I am standing outside of a building talking about the wallpaper on the inside. But to give a simplified hypothesis, no (even though I believe we will be in fellowship with each other) because apparently everyone will be "married" to Jesus (indeed it sounds unappealing when contemplated from the flesh). All will be resurrected beings with divine properties rather than adhering to secular practices bound in imperfection. Marriage as defined by the Bible is a gift and partnership, and is adequately symbolic of the more eternal marriage between believers and Jesus. Matthew 22:29-30 says, "You are mistaken, not understanding the Scriptures, or the power of God. For in the resurrection they neither marry, nor are given in marriage, but are like angels in heaven."
