I want to share with you a link to a blog post from Desiring God from back in October of 2010. It is a short post on what it means to have a hard heart. I am also attaching a couple of John Piper's sermons on this subject. I hope it is helpful. I think that I have been struggling with hard heartedness in my life. Many of the cares and the worries of this life have been haunting me lately and it is affecting my relationship with God, my family, and others. I ask for your prayers and encouragement. God bless.
