Notice: The following conclusions presented below are those of this author. There is a considerable amount of subjective matter and in other words, there exists no scriptural descriptive or explanatory details of some of these remarks. However, after having spent a number of years of meditation and study of this subject, I believe much of this information presents a reasonable description of what will be in eternity, by forming conclusions from points which are clear. They are by no means intended to be dogmatic or authoritative.
Read this verse of scripture to help us get started. It is a short verse yet it clearly details that God created man from inanimate materials and then breathed life into him. And in the case of man, his life was that of a soul, or spirit, and we learn through subsequent scriptures that this part of man is eternal, indestructible,
"And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul." (Genesis 2:7 KJV)
An almighty, all wise, all knowing God who has existed forever, is beyond the imagination of mortal man whose body is temporary and atrophic. And although God created man with an eternal soul which will never deteriorate, He fashioned man's physical being so as to control the soul while the body lives.
The soul is in the image of God and certainly has extraordinary capabilities, which when death overcomes the body, the soul (mind, mentality) will be released and will be capable of knowing and understanding an enormous amount more than while confined in the human brain and nervous system. The soul, being non-physical, does not grow, age or experience changes which are common while a part of man's physical matter. When death comes, the spirit, or soul is released in its fullness.
You see, when restricted to the confines of the brain, the mind must have electronic paths to travel. Every new thing that a person learns, from birth to death, is recorded on the brain and the mind is dependent upon those paths to bring back the thought or knowledge sought. But when released from the physical portion of man, there remains no paths for the intellect. All those things, or at least all that God desires that we know, will be retained forever.
The above is not intended to suggest that those who were in Christ at the time of death will suddenly be omniscient or omnipotent as are the triune Godhead. But we will know everything we need to know. We will not have to move around in heaven to learn the way and the 'ropes'.
Some often ask if we will know each other when we reach heaven. The answer is, of course! And it is not outside the realm of possibility that we will know every person who is in heaven! There are so many things that are incomprehensible that we cannot imagine just how things will be, but once we are there, all will be made known to us.
Some of the necessary ramifications from the above conclusions are that those whose minds were thwarted perhaps from a birth defect or other abnormality, plus those tiny fetuses that have been murdered, and the myriad other factors which may be taken into consideration, will be full grown spirits and free from all of the detrimental factors. The murdered fetuses will stand in judgment of those who performed their deaths and those who consented to it.
There are other questions which will, no doubt, be answered. Many people spend much of their lives saddened over the fact that their parents, their children, or any other loved ones, were not living righteous lives when they died. There is a possibility that those memories will be erased, by God, so that there will be no further anxiety. We do know that there will be no sadness, no pain, no dying. Read this passage of scripture and even though partially written in symbolic language, consider seriously what is described:
"And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful. And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely. He that overcometh shall inherit all things; and I will be his God, and he shall be my son. But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." (Revelation 21:1-8 KJV)
John writes that he saw a new heaven and new earth for the first heaven and first earth had passed away. John is apparently using that term to refer to earth and the universe which is now some times referred to as the heavens in scripture. The heaven which is the abode of Jesus and the Father, will never pass away. The new earth and new heaven must have reference to that place of 'many mansions' which Jesus refers to. We do know for sure that the old earth and indeed the entire universe shall be completely passed away by the assurance of such by the apostle Peter. Please take the time to read the 3rd chapter of 2 Peter as he describes the total obliteration of physical matter. Here is a brief portion of his message:
"But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up." (2 Peter 3:10 KJV)
Notice that 'elements' mean even the tiniest molecule shall be dissolved. In brief...all physical matter. Before the creation, none of this existed, and after this event, none will exist anymore. There will be no physical matter in heaven. Read these verses:
"Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption." (1 Corinthians 15:50 KJV)
"Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is." (1 John 3:2 KJV)
"We shall see him as he is" has reference to Jesus when he returns and we will be "like him". Jesus is a spirit, we will be spirits. Man cannot see a spirit, because they are in no wise physical, therefore they do not reflect light into our eyes and thereby give us visual images.
When John says above, "it doth not yet appear what we shall be", he says a mouthful. If this inspired apostle could not speak words that would identify what the spirit consists of, certainly this writer would not even venture a guess. But for a certainty it will not be physical in any way.
It may be that God has the ability and the desire to make us appear as physical and be seen in spirit as in physical reality. But we must consider that all things which are physical will be gone. The physical man has physical desires, hunger, thirst, sexual desires, others, but they are all desires of the flesh...physical. We also have physical pain in many, many ways. We have emotions and from those emotions, we have sadness from many situations, We have sickness when some physical parts are infected with viruses, bacteria and other such thing. All physical problems.
But the proof that we will not be physical in any way is shown by these verses:
"And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away." (Revelation 21:4 KJV)
"But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage:" (Luke 20:35 KJV).
You see, all the references above refer to physical characteristics, of which there will be none. There are no women or men in heaven. There are former men and women in heaven. Spirits are gender neutral. True, there are many references to individuals and they are always referred to by the male gender, but that does not infer or mean that they are male as those people and animals on earth. The differences in male and female are physical, of such there are none in heaven.
We cannot comprehend eternal life in heaven or hell. But we must try and thereby strive to enter the strait gate. Some have asked me from time to time, what will we do in heaven? And all I can say is I do not know, but I do know that we will be in the care of our Father in heaven who has all knowledge, all wisdom, all power and is forever present. He can do anything whatsoever that He desires, as is witnessed by this incomprehensible universe and all that is in it. We know that he loves us and his highest desire is that we abide with him in happiness and glory in heaven forever. What else can one ask?
