Matthew 22:29-39

29 Jesus answered, "You're off base on two counts: You don't know your Bibles, and you don't know how God works.
30 At the resurrection we're beyond marriage. As with the angels, all our ecstasies and intimacies then will be with God.
31 And regarding your speculation on whether the dead are raised or not, don't you read your Bibles? The grammar is clear: God says,
32 'I am - not was - the God of Abraham, the God of Isaac, the God of Jacob.' The living God defines himself not as the God of dead men, but of the living."
33 Hearing this exchange the crowd was much impressed.
34 When the Pharisees heard how he had bested the Sadducees, they gathered their forces for an assault.
35 One of their religion scholars spoke for them, posing a question they hoped would show him up:
36 "Teacher, which command in God's Law is the most important?"
37 Jesus said, "'Love the Lord your God with all your passion and prayer and intelligence.'
38 This is the most important, the first on any list.
39 But there is a second to set alongside it: 'Love others as well as you love yourself.'
