The doctrine of the immortality of the soul within protestantism is much like the theory of evolution in the world. In both cases its adherents believe they have to accept it. They believe there is no other way. Both of these ideas are taught by high ranking seminaries and universities. They are both hypnotic in their effects. Pauls counsel to Timothy could be seen as appropriate here.
1 Timothy 6:20 KJV
O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:
Just as it is stretching incredulity to believe that all this wonderful creation by which we are surrounded happened through some random chemical reaction or “big bang”. So it is also stretching incredulity to believe that the God of love who created all things would impose immortality on his creation so that He can punish them for eternity. In some theologians view this is supposed to show ‘His love’. When the Bible says:
Nahum 1:9 KJV What do ye imagine against the Lord ? he will make an utter end: affliction shall not rise up the second time.
When it says: 1 Timothy 6:16 AMP He alone possesses immortality [absolute exemption from death] and lives in unapproachable light, whom no man has ever seen or can see.
When it says of the new earth: Revelation 21:4-5 KJV And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.  And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
God is dependable and wonderful. Too wonderful for us to comprehend. But totally dependable.
