20 There were seven brethren; and the first took a wife, and dying did not leave seed; 21 and the second took her and died, and neither did he leave seed; and the third likewise. 22 And the seven [took her and] did not leave seed. Last of all the woman also died. 23 In the resurrection, when they shall rise again, of which of them shall she be wife, for the seven had her as wife? 24 And Jesus answering said to them, Do not ye therefore err, not knowing the scriptures, nor the power of God? 25 For when they rise from among [the] dead they neither marry, nor are given in marriage, but are as angels [who are] in the heavens. 26 But concerning the dead that they rise, have ye not read in the book of Moses, in [the section of] the bush, how God spoke to him, saying, I [am] the God of Abraham, and the God of Isaac, and the God of Jacob? 27 He is not the God of [the] dead, but of [the] living. Ye therefore greatly err.

The Great Commandment

28 And one of the scribes who had come up, and had heard them reasoning together, perceiving that he had answered them well, demanded of him, Which is [the] first commandment of all? 29 And Jesus answered him, [The] first commandment of all [is], Hear, Israel: the Lord our God is one Lord; 30 and thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thine understanding, and with all thy strength. This is [the] first commandment. 31 And a second like it [is] this: Thou shalt love thy neighbour as thyself. There is not another commandment greater than these. 32 And the scribe said to him, Right, teacher; thou hast spoken according to [the] truth. For he is one, and there is none other besides him; 33 and to love him with all the heart, and with all the intelligence, and with all the soul, and with all the strength, and to love one's neighbour as one's self, is more than all the burnt-offerings and sacrifices.

Commentary on Mark 12:18-27

(Read Mark 12:18-27)

A right knowledge of the Scripture, as the fountain whence all revealed religion now flows, and the foundation on which it is built, is the best preservative against error. Christ put aside the objection of the Sadducees, who were the scoffing infidels of that day, by setting the doctrine of the future state in a true light. The relation between husband and wife, though appointed in the earthly paradise, will not be known in the heavenly one. It is no wonder if we confuse ourselves with foolish errors, when we form our ideas of the world of spirits by the affairs of this world of sense. It is absurd to think that the living God should be the portion and happiness of a man if he is for ever dead; and therefore it is certain that Abraham's soul exists and acts, though now for a time separate from the body. Those that deny the resurrection greatly err, and ought to be told so. Let us seek to pass through this dying world, with a joyful hope of eternal happiness, and of a glorious resurrection.

Commentary on Mark 12:28-34

(Read Mark 12:28-34)

Those who sincerely desire to be taught their duty, Christ will guide in judgment, and teach his way. He tells the scribe that the great commandment, which indeed includes all, is, that of loving God with all our hearts. Wherever this is the ruling principle in the soul, there is a disposition to every other duty. Loving God with all our heart, will engage us to every thing by which he will be pleased. The sacrifices only represented the atonements for men's transgressions of the moral law; they were of no power except as they expressed repentance and faith in the promised Saviour, and as they led to moral obedience. And because we have not thus loved God and man, but the very reverse, therefore we are condemned sinners; we need repentance, and we need mercy. Christ approved what the scribe said, and encouraged him. He stood fair for further advance; for this knowledge of the law leads to conviction of sin, to repentance, to discovery of our need of mercy, and understanding the way of justification by Christ.
