Ezekiel 11:19-21–And I will give them one heart, and a new spirit I will put within them. I will remove the heart of stone from their flesh and give them a heart of flesh, 20  that they may walk in my statutes and keep my rules and obey them. And they shall be my people, and I will be their God. 
One of the things that has helped me fight to get “in touch” with my spirit, now that I know Christ, was how much I avoided it when I was “unsaved”.  So much of my identity came from my job, achievements, hobbies, etc.  In other words things that enhanced my flesh, and the more I prioritized those things, the harder my heart was to my spirit/emotions…
I am not saying, that those things that are considered “fleshly” are not important to take care of.  The issue was the order of importance in which I did take care of them.  Instead of taking care of those things with a heart that was sensitive to God and His Word, it was hardened and completely detached from Him, and what desperately needed to be taken care of…(Proverbs 24:30-34)
The irony is, that you don’t have to be an unbeliever to live in such a condition.  Not making time to deal with our heart, and whether it is responsive to God and His Word, can leave us just as hardened and “detached”.  Generally we would say prayer is the remedy to this issue.  But even prayer can be “lifeless”, without really dealing with what may be hardening our heart at the root…
The Lord was making sure Ezekiel understood, that His people were so entrenched in their flesh and idolatry, that they needed a new heart and spirit to see their condition.  Though Israel would go through all the “motions” of worship, they were so detached from God, that any move of the Spirit was met with “stone”. Of course God’s desire was for them to have a “heart of flesh”, that sought unity and truth through His love and faithfulness… 
For myself, I’ve learned that I must take time not only to read the Word, but be honest about how hardened I am towards things I should be sensitive to.  That the Lord promises to cleanse my heart of all unrighteousness when I confess to Him.  This promise has helped me to at least acknowledge my hardness, rather than pretend I don’t have any.  I’ve learned that dealing with emotional issues instead of avoiding them, is made easier when my heart is sensitive to the Lord.  Challenge yourself to be honest about how hardened you may be.  Denial is a sign of unbelief, that God can’t give you a heart of flesh to unify and walk in love with Him, and the people you may be hardened against.
