“Go to this people and say, ‘You will be ever hearing but never understanding; you will be ever seeing but never perceiving.’  For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes.  Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.”

This can happen to us.  If we neglect our time in God’s Word, if we choose to do things our way instead of the way God has clearly laid out for us, we too can become calloused and hard-hearted.  We will know it when this happens.  When what WE WANT becomes more important than what God wants, when having our own way is more important than the needs of others, we are on our way to a calloused heart.
