Mark 12:29

25For when they will rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven.

26But about the dead, that they are raised, haven’t you read in the book of Moses about the Bush, how God spoke to him, saying, ‘I am the God of Abraham, the God of Isaac, and the God of Jacob’?

27He is not the God of the dead, but of the living. You are therefore badly mistaken.”

28One of the scribes came and heard them questioning together, and knowing that he had answered them well, asked him, “Which commandment is the greatest of all?”

29Jesus answered, “The greatest is: ‘Hear, Israel, the Lord our God, the Lord is one.

30You shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment.

31The second is like this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”

32The scribe said to him, “Truly, teacher, you have said well that he is one, and there is none other but he;

33and to love him with all the heart, with all the understanding, all the soul, and with all the strength, and to love his neighbor as himself, is more important than all whole burnt offerings and sacrifices.”
