You posting Paul writing over the prophets. If the prophet already have spoken concerning the dead why do you doubt the prophets, in the first place? 2 Peter 1:21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost. The prophets had the Holy Ghost to, they no the word of God before Paul.
Solomon says in Ecclesiastes 9:5 For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
For the living know not any thing, neither any more reward. Why? Once you're dead there is no more hope. If you went to the grave in Christ, he will awake you in the first resurrection, and you will live and reign on the earth with him and the saints. If you did not die in Christ he will wake you in the second resurrection and you will be judged according to your works. If you are dead do you have any memory? What did Solomon say? "For the memory of them is forgotten". Now we know you have no more memory while you are in the grave. If you did something wrong to a person and they're dead, you don't have to worry, they won't come and haunt your house.
Solomon said in Ecclesiastes 9:6 Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun.
This verse speaks for itself. To put it short you don't remember anything while you are in the grave. Why does he continue to say "under the sun"? He's said it twice. We will find out a little later.
Ecclesiastes 9:10 Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave whither thou goest.
If there is no work, no device, no knowledge, no wisdom, in the grave, why does
he status quo say there are spirits that walk the earth? They have no knowledge of the Word of God. There are spirits that walk the earth, but they are not dead people.
If Paul and Solomon was alive you would be starting a argument between them to.
