Mar 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? 27 He is not the God of the dead, but the God of the living: ye therefore do greatly err.
DPMartin, I ask you to consider "He is not the God of the dead, but the living" was before Christ's death and resurrection. Much like Jesus' words spoken in Mark 7:27 But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs.
It was not yet time.
We know now that through Christ's death and resurrection He did indeed cast the children's bread to the dogs. He also is a God of the dead. Death and resurrection.
The dead rise.
Mark 12:26-27 KJV
[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? [27] He is not the God of the dead, but the God of the living: ye therefore do greatly err.
Numbers 19:13 KJV
[13] Whosoever toucheth the dead body of any man that is dead, and purifieth not himself, defileth the tabernacle of the Lord ; and that soul shall be cut off from Israel: because the water of separation was not sprinkled upon him, he shall be unclean; his uncleanness is yet upon him.
Numbers 19:18 KJV
[18] And a clean person shall take
hyssop, and dip it in the water, and sprinkle it upon the tent, and upon
all the vessels, and upon the persons that were there, and upon him that touched a bone, or one slain, or one dead, or a grave:
John 19:29 KJV
[29] Now there was set a vessel full of vinegar: and they filled a spunge with vinegar, and put
it upon hyssop, and put it to his mouth.
Psalm 51:7 KJV
[7] Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
Hebrews 9:19-23 KJV
[19] For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people, [20] Saying, This is the blood of the testament which God hath enjoined unto you. [21] Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry. [22] And almost all things are by the law purged with blood; and without shedding of blood is no remission. [23] It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
After His death and resurrection:
He is a God of the living and the dead.
