Jesus said in Matt 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
It appears Jesus saw the difference in body and soul and that the body could be killed but the soul would live.
God was manifest in the flesh and also possessed a body and soul just as a man would. However he died as a man that was cursed of God as a law breaker under the law.
Galatians 3:13 "Cursed is every one that hangeth on a tree." But when Christ's body was in the tomb his soul was descended into the lower parts of the earth, but was not left there.
His soul was active and led captivity captive. Unless one would believe the Spirit of God descended into the lower parts of the earth we must conclude that it was his human soul and yet his body was dead awaiting the Resurrection which took place three days later.
But concerning them that are asleep/dead in Christ under grace and not the law If Jesus' soul did not sleep even for the three days he was in the grave. Would our soul be active, alive, asleep, inactive where will our soul be? We will not descend into hell.
So what is the location of saved souls before the resurrection?
