Luke 20:38

he is not a God of the dead, but of the living Rather, of dead beings, but of living beings. The Pharisees had endeavoured to draw proofs of immortality from the Law, i.e. from Numbers 15:31. In later times they borrowed this proof from Christ, lighting their torches at the sun though they hated its beams. But they had, up to this time, offered no proof so deep and true as this. The argument is that God would never have called Himself "the God of Abraham, of Isaac, and of Jacob," if these Patriarchs, after brief and sad lives, had become mere heaps of crumbling dust. Would He have given confidence by calling Himself the God of dust and ashes? So Josephus (?) says, 4Ma 16:24, "they who die for God's sake, live unto God as Abraham, Isaac, and Jacob, and all the Patriarchs." Acts 17:28.

for all live unto him Romans 14:8-9. Our Lord added, "Ye therefore do greatly err." But how incomparably less severe is the condemnation of religious and intellectual error, than the burning rebuke against Pharisaic lovelessness!
