Trusting Christ

My heart has softened from what it used to be.  I'm convinced that the hard-heartedness I often struggle with is due to some kind of lie about God, that He's not kindly disposed towards me, that His offer of grace has some hidden obligation.  The Bible says in Psalm 34:8 "Taste and see that the Lord is good..."  Well I have and I have seen that the Lord is good.  I want that back, that trust I had in God and His character.  I want to know that once again.
