In the time when Eccl. was written, no man had the permanent indwelling of God's Holy Spirit! Therefore, no man ever had a spirit of any kind, that it should go back to God!
only questions. Get the ‘no permanent in indwelling of God’s Holy Spirit’ but not the no man had
a spirit of any kind, that it should go back to God. 1) is to be converted not to turn again, return again to God? ‘hear My voice and turn’; Born again? Born anew? Luke 22:31-32 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat: [32] But I have prayed for thee, that thy faith fail not: and
when thou art converted, (turn again, return) strengthen thy brethren. Matthew 18:3
2) no man had
a spirit of any kind, that it should go back to God.
Question whether that is a true assertion: Christ turned and rebuked them saying you know what spirit you are of. Also,
2 Timothy 1:7 For God hath not given us
the spirit of fear; but of power, and of love, and of a sound mind.
Romans 8:15-16 For ye have not received
the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. [16]
The Spirit itself beareth witness with our spirit, that we are the children of God:
1 Corinthians 2:11-12 For what man knoweth the things of a man,
save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. [12] Now we have received,
not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
so to say ‘no man had
a spirit of any kind, that it should go back to God.’ Unless I’ve misunderstood His word says before conversion (to turn again, return to God being born anew having received the Spirit of God bearing witness with our spirit that we are children) man does have a spirit apart from God: having received ‘the spirit of bondage’ ‘the spirit of fear’ ‘the spirit of the world’ being in torment as legion hiding out in the caves, cutting himself with stones, fettered and in shackles which no man could tame him ...but perfect love cast out torment. The spirit of fear, the spirit of bondage...
