23 So tell us, whose wife will she be in the resurrection? For all seven were married to her." 24 Jesus replied, "Your mistake is that you don't know the Scriptures, and you don't know the power of God. 25 For when the dead rise, they will neither marry nor be given in marriage. In this respect they will be like the angels in heaven. 26 "But now, as to whether the dead will be raised-haven't you ever read about this in the writings of Moses, in the story of the burning bush? Long after Abraham, Isaac, and Jacob had died, God said to Moses, 'I am the God of Abraham, the God of Isaac, and the God of Jacob.' 27 So he is the God of the living, not the dead. You have made a serious error."
28 One of the teachers of religious law was standing there listening to the debate. He realized that Jesus had answered well, so he asked, "Of all the commandments, which is the most important?"

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.
