Mark 12:30

27 He is not the God of the dead, but of the living: ye do greatly err.

28 And one of the scribes came, and heard them questioning together, and knowing that he had answered them well, asked him, What commandment is the first of all?

29 Jesus answered, The first is, Hear, O Israel; The Lord our God, the Lord is one:

30 and thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength.

31 The second is this, Thou shalt love thy neighbor as thyself. There is none other commandment greater than these.

32 And the scribe said unto him, Of a truth, Teacher, thou hast well said that he is one; and there is none other but he:

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