You seem to think of Stephen's spirit as something separate from his body. Consider Genesis 2:7Homer wrote:When Stephen was stoned to death in Acts 7:55-60 we see Stephen filled with the Holy Spirit and he sees Jesus "standing" at the right hand of God and he says "Jesus, receive my spirit...". It seems Stephen expected to be with the Lord that day, the future tense is not used.
Then the Yahweh God formed the man of dust from the ground and breathed into his nostrils the breath (spirit) of life, and the man became a living being (soul).
Here we have the first man—his entire being: body and "spirit" united to form a single entity, inseparable. For the man's spirit was simply the breath of life which God breathed into him. When the man was alive, he was a living being (soul). He didn't receive a soul; he was a soul—that is, he was a being—a living being.
The writer of Ecclesiastes described death this way:
... and the dust returns to the earth as it was, and the spirit returns to God who gave it. (Eccl 12:7)
That which is dust, the human body, returns to the earth, after death, and becomes part of it. But the spirit of life which God originally breathed into man, returns to God. There is no indication here that the spirit is the "real you", which inhabits the body and can exist without the body as a conscious entity.
I know nothing about "soul sleep". It is not my position. The concept makes no sense to me unless its proponents think of the soul existing as a separate entity apart from the body, continuing to exist after death, but in a state of unconsciousness until the resurrection. If that is what is meant, I don't know anyone who actually holds that position. I have never heard of anyone who claimed to hold that position. The term seems to be used exclusively by those believe in the continuation of consciousness after death to describe those who don't so believe.Consider this:
Luke 23:46 (NASB)
46. And Jesus, crying out with a loud voice, said, “Father, into Your hands I commit My spirit.” Having said this, He breathed His last.
If Jesus in the tomb experienced "soul sleep", His cry from the cross makes no sense; His spirit would not have left to go anywhere.
I am not sure whether by "My spirit" Jesus meant the spirit of life which He received by being conceived and born, the life inherited from His mother, that spirit of life which every human has, or whether He meant His consciousness, the divine Person who pre-existed as the Son of God, begotten before all ages.
I am inclined toward the former, in which case, He may not have existed as a conscious entity after death until He was resurrected. Then He was able to extend His consciousness into his disciples, and so communicate with them. "Behold I am with you always even to the end of the age." Though I am not dogmatic about Jesus' case, it makes more sense to me that He actually died like any other man. I think He spent three days "in the heart of the earth" (in His tomb) like any other man, and then God raised Him from the dead (He couldn't raise Himself; He was dead).
If the latter is the case, then He may have continued in consciousness and gone directly to the Father immediately after His death. But since He was FULLY human (not ½ God and ½ man while He was on earth), I doubt this to be the case. I think He had to become 100% human while He was on earth, in order to provide salvation for humanity. As a total human being, He demonstrated by His life that it is possible for a human being, by the enabling grace of God, to live sinlessly. All the miracles which Jesus supposedly performed, were actually the work of the Father through Him. Jesus once said, "I do nothing from myself." (John 8:28)
