In Luke 20, Jesus is continually being put to the test by the Jewish leaders who did not trust Him. They sent men to spy on Him and tried to frame Him by asking Him questions that they thought would cause Him to say something incriminating.
Yet Jesus never stumbled. They stumbled over Him. His answers left them speechless and amazed at His authority and His understanding of the Scriptures. Sadly, this did not sway them to trust in Him as their Lord and Savior.
The Sadducees did not believe in the resurrection and were hoping to catch Jesus off guard by giving Him a scenario about a woman whose husband died. The husband had seven brothers. One by one, She married brother after brother and they each died leaving her no children. Being a widow 8 times over, The Sadducees asked Jesus, "In the resurrection, whose wife will the woman be?"
Jesus answered, The sons of this age marry and are given in marriage, but those who are considered worthy to attain to that age and the resurrection from the dead neither marry nor are given in marriage, for they cannot die anymore, because they are equal to angels and are sons of God, being sons of the resurrection. But that the dead are raised, even Moses showed, in the passage about the bush, where he calls the Lord the God of Abraham and the God of Isaac and the God of Jacob. Now he is not God of the dead, but of the living for all live to him."
Those who have not been found worthy because they never believed in Jesus Christ as their Lord, will be found dead in their sins and will be raised up from the grave for judgement. Yet, those who are considered worthy are sons of the resurrection. Did you catch that? When we repent of our sins and give our life to the Lord, we have been made alive through Jesus Christ. Like Him, we are now a child of the Father and because of Christ's death for our sins, we have been made alive and will live to God forever.
"Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, that everyone who believes in Him may have eternal life. For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.…" John 3:14-16
“Behold, the dwelling place of God is with man, and He will live with them. They will be His people, and God Himself will be with them as their God. He will wipe away every tear from their eyes, and there will be no more death or mourning or crying or pain, for the former things have passed away.” And the One seated on the throne said, “Behold, I make all things new.” Revelation 21:3-5
