Mark 12:26
And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob?
The verse is Christ's answer to the Sadducees in their denial of the resurrection. Those questioners also rejected future rewards and punishments, and they brought the case of a woman who had seven brothers as husbands to entangle Him, to heap ridicule on the law of Moses, and to bring all the Mosaic institutions into contempt. In reply He exposed their false foundation and false premises and charged them with greatly erring through ignorance of the Scriptures and the power of God. He silenced them with dignity and power.
By citing what God spoke to Moses in the bush about being the God of Abraham and the God of Isaac and the God of Jacob, He proved that the dead rise, because God is not the God of the dead but of the living. So the patriarchs must live again, and the dead live to Him. If there is no resurrection, the Scriptures are of no avail. God sees His purpose for the dead as already accomplished.
The verse promises that the precious dead from Abel down to the last saint who dies will hear the voice of the Son of God, come forth from their graves, and live again to immortal life. God will be their God and they will be His people, and there will be a close and tender relationship between God and His resurrected saints in accordance with the divine plan.
The verse is part of words that warn people in every age who refuse to receive Him as Redeemer; the warning applies to every sinner, and the doom foreshadowed will be theirs unless they repent. A right understanding of the Scriptures is the fountain from which flows all pure, heavenly knowledge.
