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. 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.
1 Thessalonians 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.

The verse from Thessalonians has absolutely no bearing on your point.
The verse from Ecclesiastes is a single verse—from the Old Testament. It is absurd to think that a single verse, out of context, from an OT book necessarily lays out developed Christian doctrine.
BTW: Jesus said to cut off your hand and pluck out your eye. Have you done it yet?
If so; there are a LOT in reply #155 to ignore as well.
