23 That same day the Sadducees, who say there is no resurrection, came to him with a question. 24 “Teacher,” they said, “Moses told us that if a man dies without having children, his brother must marry the widow and raise up offspring for him. 25 Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. 26 The same thing happened to the second and third brother, right on down to the seventh. 27 Finally, the woman died. 28 Now then, at the resurrection, whose wife will she be of the seven, since all of them were married to her?”
29 Jesus replied, “You are in error because you do not know the Scriptures or the power of God. 30 At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven. 31 But about the resurrection of the dead—have you not read what God said to you, 32 ‘I am the God of Abraham, the God of Isaac, and the God of Jacob’? He is not the God of the dead but of the living.”
33 When the crowds heard this, they were astonished at his teaching. Matthew 22:23-33
I’ve always been puzzled about this passage myself.
BibleHub discusses this passage a bit, and it’s but one man’s opinion since the Bible does not address the topic at length:
The risen life is no mere reproduction of the present, but a regeneration, new life added to the old, with new powers, acting under new laws, ranged in a new community. On earth men are mortal, and marriage is necessary to perpetuate the race; no such necessity obtains in the other life, where men are immortal…Thus Christ, in opposition to the Saddueces’ creed, admits the existence of angels. Glorified men are like the angels in these characteristics especially. They are immortal, no longer subject to human wants, passions, failings, or temptations; they serve God perfectly without weariness or distraction; they have no conflict between flesh and spirit, between the old nature and the new; their life is peaceful, harmonious, satisfying.
We can still be in awe of the risen life. In fact, we should be.
As the Bible says, we see but a glass darkly (1 Corinthians 13:12 KJV). We’re only seeing through a fog, the fog of sin and corruption and what we know to be true here on earth. We’re very limited in what we can see.
Sometimes we are treated to gorgeous sunrises and sunsets, mountain vistas, and awe-inspiring star-lit nights.
What God has prepared for His children will be significantly better than even the best natural views here. We won’t be bored, frustrated, lonely, or in pain there.
Relationships will be different and more fulfilling there. Our old nature with its greed and bitterness and strife will be past tense.
Until then, we slog away day after day wanting and hoping to make a difference in someone else’s life.
And that’s a good thing.
