Where I wind up is that God knows best and whatever He has put together will be far more pleasurable than what we have here.
Exactly.
From my study of scripture, I believe that there will be no marriage or individual marriage relationships in Heaven because it will be unnecessary. Relationships exist on earth for companionship and mutual benefit. Family relationships exist for protection, provision and socialization. The ideal family equips the child to grow into a caring, responsible adult. God created marriage to teach us human beings to live entirely for another, loving and cherishing another human being more than oneself. According to Ephesians 5, the ideal marriage forms a picture of the relationship Christ has with us, the husband demonstrating the love and care of Christ toward his wife; and the wife demonstrating the love and honor of Christ toward her husband. Thus the two form a perfect and stable environment of love for those whom they bring into the family through birth or adoption.
But none of this will be necessary in Heaven. We, individually and collectively, will be married to Christ in a perfect, intimate, harmonious relationship. We will be one with God (1 Corinthians 6:17; John 14:20) in spiritual union (John 17:20-23), though not of essence for there is only one God (Deuteronomy 6:4). But we will be one with Him in the sense that we will then know perfectly, even as we are now known by Him (1 Corinthians 13:12), and we will in fact be like Him (1 John 3:2), seated with Him in Heavenly places, ruling and reigning with Him (Ephesians 2:6; Revelation 3:21, 20:4).
In fact, every single person who enters Heaven will enjoy that same perfect union with God. Which means that, if each of us is in perfect union with God, we will unavoidably be in perfect union with each other. Just as we are with God. There will be nothing that can separate us. The union which we had with our spouse on earth --as perfect and delightful as it may be-- will pale by comparison to the union we will have with God and every other soul in Heaven. What an incredible thought!
In no way does this mean that our relationship with our earthly spouse will be less in Heaven. Not at all. There will be no loss: only gain. Our relationship with our spouse will be perfect there. Far, far greater than anything we have known on earth. But we will have that same absolutely perfect relationship with every other single soul in existence, the same perfect relationship we will have with God. Can you imagine? Everything will be perfect. Including our relationships. Every single one. Total union of heart and mind! Perfect. Forever.
Truly our joy will be full!!!
Search the Scriptures. Don't try to impose what we know of existence on them. Simply let them speak to you and see if you do not find hints of what I have just said.
But that said, how that will feel, how we will function, how we will be separate souls yet united in perfection, with no trace of sadness but only eternal happiness? I do not know. I cannot imagine such an existence. It is beyond my ability to conceive. But I do know this-- it will be far, far greater; far, far more exciting; far, far more wonderful; far, far more fulfilling than anything you or I could ever imagine. Glory to God!!!
Even so, come Lord Jesus.
