Mark 12:18-27
Marriage at the Resurrection
18 Then the Sadducees, who say there is no resurrection, came to him with a question. 19 "Teacher," they said, "Moses wrote for us that if a man's brother dies and leaves a wife but no children, the man must marry the widow and have children for his brother. 20 Now there were seven brothers. The first one married and died without leaving any children. 21 The second one married the widow, but he also died, leaving no child. It was the same with the third. 22 In fact, none of the seven left any children. Last of all, the woman died too. 23 At the resurrection whose wife will she be, since the seven were married to her?"
24 Jesus replied, "Are you not in error because you do not know the Scriptures or the power of God? 25 When the dead rise, they will neither marry nor be given in marriage; they will be like the angels in heaven. 26 Now about the dead rising—have you not read in the book of Moses, in the account of the bush, how God said to him, 'I am the God of Abraham, the God of Isaac, and the God of Jacob'? 27 He is not the God of the dead, but of the living. You are badly mistaken!"
1 Corinthians 15:3-8
Jesus Appeared to His Brother James and Others After His Resurrection
3 For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Cephas, and then to the Twelve. 6 After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles, 8 and last of all he appeared to me also, as to one abnormally born.
Acts 1:1-3
Jesus Appeared to His Disciples Over a Period of Forty Days
1 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach 2 until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. 3 After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God.
Jesus makes it clear that there will not be marriage in heaven, when He says, " When the dead rise, they will neither marry nor be given in marriage; they will be like the angels in heaven."...So there will be no marriage in heaven...We may know our wife or wives and love them as we love the others in heaven...We will know our brothers and sisters and meet them in heaven...I believe when Jesus met His brother James after His death and resurrection is a sign of this...And Jesus met with His Disciples for forty days after His death, which shows that we will meet up with friends after our deaths...
