"Spiritual" actually refers to the "inner SELF" (the mind) of a person (individuality).
A person can have a...
...peaceful spirit, fighting and protective spirit of a soldier, team spirit of a sports player, caring spirit, Godly spirit, etc.
OUR spirit is supposed to be compatible with GOD'S eternal spirit...
Romans 8:16
"it is the Spirit Himself bearing witness with OUR SPIRIT that we are children of God".
That "40 minutes" is a bit excessive (is your ambition to be an artist, biologist, weight trainer, etc.)?
I'm 55 years old and I know how negative childhood experiences can effect us for life (I suffered 51 years of suicidal depression). A bad childhood often causes low self esteem and sometimes we feel that we are the only one who will admire us.
There is an attitude that is encouraged almost universally in all denominations (it is a FALSE teaching that is VERY dangerous to the human being...it's called SELF abasement and The Lord didn't warn against for no reason).
It doesn't simply refer to putting yourself down (belittling yourself), it refers to IDENTITY abaTement (surrendering your individuality). It is dehumanizing and demoralizing (you can no longer think/reason as a free thinking human being).
Colossians 2:18
"Let no one DISQUALIFY you insisting on self abasement...".
It seems like the inner human being is 'crying out' and wants to be recognized (SELF realization is necessary to be able to relate to and identify with "I am who I am", Exodus 3:14, and have a 2 way PERSONAL relationship with The Lord).
Don't "surrender" your spirit/SELF to God ("relate to" God and SHARE your spirit with Him in a "personal" relationship with all your IDIOSYNCRACIES/quirks, habits, shortcomings, etc.).
There is alot to learn about God that has never been understood because of "self abasement" (it really does prevent the proper thinking of the human being, but psychologically, it also causes the 'inner human being' to want to 'know itself' and admire who we really are, simple "UNDERSTANDING" is like gold...Proverbs).
Some of the things that were never understood and realized are below...
=====================================
We are the "living stones" (inner temple) and Jesus is the "cornerstone" (outer temple)...
 
John 2:19 and 21
"three days"...."the temple..." (outer temple AND third temple).
 
1 Corin. 3:16 and 6:19
"you are God's temple..." (inner temple, we have already been transferred into His kingdom, Colossians 1:13 if we are spiritually INside Jesus's body...NEW/spirit creation).
 
1 Peter 2:4, 5
"Come to Him, to that living stone..."..."and like living stones,...".
 
Let the "living" water (1 John 5:6, John 7:38, Acts 1:5) baptize/consecrate the inner temple to the third temple/outer temple and "neither thirst" (Revelation 7:16).
 
Amos 5:21
"I hate, I despise your feasts and your solemn assemblies".
 
We should live under the PERFECT law (James 1:25 and 2:12) because of what Jesus accomplished (Ephesians 2:15) and keep our devotion/relationship private between each of us and God...
 
Romans 14:22
"The faith that you have, keep between yourself and God".
God knows where you're at in your life. The most important thing is that you love Him very much (LOVE for God changes the whole picture). Instead of only believing in Him, you also trust Him, then you will have a "faith for faith"...(because you wish to 'draw closer', Romans 1:17).
Hebrews 11:6
"that He exists...".....(and ALSO BELIEVE He rewards).
KNOW THYSELF. With a little deep and profound thought, you can be the physician.
Luke 4:23
"Physician, HEAL THYSELF"....in the KJV. (The Lord's words are PRINCIPLES that apply in all parts of life).
