I don't care if demons has the ability to impersonate the dead. What matters is what the Bible tells us and it tells us that Samuel came back and spoke to Saul.
Samuel did not have a choice in the matter, He was brought back to speak to Saul by God and Samuel prophesied correctly and delivered God's sentence onto Saul.
1Sam 28:16 Samuel said, “Why do you consult me, now that the Lord has departed from you and become your enemy? 17 The Lord has done what he predicted through me. The Lord has torn the kingdom out of your hands and given it to one of your neighbours—to David. 18 Because you did not obey the Lord or carry out his fierce wrath against the Amalekites, the Lord has done this to you today. 19 The Lord will deliver both Israel and you into the hands of the Philistines, and tomorrow you and your sons will be with me. The Lord will also give the army of Israel into the hands of the Philistines.”
The life that Jesus regained is the life that He laid down as a ransom for many.
John 10:17 The reason the Father loves Me is that I lay down My life in order to take it up again. 18
No one takes it from Me, but I lay it down of My own accord. I have authority to lay it down and authority to take it up again. This charge I have received from My Father.”
He laid down the life of His body and laid down His body,,,,,,,,,,,,as ransom.
He regained to life of the body and regained the body, as the scriptures tell us. (John 2:19-22 etc)
I think it is amazing what the glorified resurrection body can do and I think you are misreading the scriptures when you describe Jesus resurrection body on different occasions.
It is against God's law to go to a medium or witch to communicate with spirits. If an angels comes to you as a spirit and speaks to you then that is not unlawful. This happened to Mary at the annunciation and at the tomb also.
Matt 28:2 There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it. 3 His appearance was like lightning, and his clothes were white as snow. 4 The guards were so afraid of him that they shook and became like dead men.
5 The angel said to the women, “Do not be afraid, for I know that you are looking for Jesus, who was crucified. 6 He is not here; he has risen, just as he said. Come and see the place where he lay.
Yes that's right, He rose bodily.
Again a moot point since I said nothing about an immortal soul and I even agreed with JW views.
Nevertheless those who are thrown into the lake of fire do suffer torment unless you deny what the Bible tells us about it. As I said, it does not say how long their torment lasts.
When Jesus spoke of the soul living on after the death of the body I don't think He was talking about an embodied spirit, do you.
"soul" sometimes means a disembodied spirit in the scriptures but JWs deny those places.
Rev 6:9 is one such place and 1Kings 17:21 would be another and Matt 10:28 would be another.
There is only one resurrection described in the scriptures and it is of the body. I think I have provided Romans 8:11 and Romans 8:23.
God would have no difficulty remembering trillions of people but that is not the point.
A copy is a copy is a copy and resurrection is not about making a copy.
If God made a copy of me now there would not be 2 of me, there would be me and my copy,,,,,,,,,,,which would not be me. It is the same if God made a copy of me after I died.
That is reading your theology into the text instead of reading it according to the use of words and understanding of the day.
Anyway the phrase that Jesus used all through the gospels was "Truly I tells you,....." never "Truly I tell you today,....."
