When we have hardened our hearts, it’s difficult if nearly impossible for God’s Word to penetrate that tough exterior. In Acts 28:27, Paul used the term “calloused hearts” when dealing with the unbelieving Jews in Rome as he quoted Isaiah 6:9-10 to them. “You will be ever hearing but never understanding; you will be ever seeing but never perceiving. For this peoples’s heart has become calloused.” Our hearts may acknowledge and even recognize that still small voice of the Holy Spirit…but when it comes time to heed His direction, we quickly turn away, refusing to obey out of rebellion and selfishness. And sadly, over time it becomes easier and easier not to obey the prompting of the Holy Spirit, for over time our hearts become more and more calloused. So if today you hear His voice, trade in your heart of stone for a heart of flesh.
In I Corinthians 4:5 it tells us that God will bring to light what is hidden in darkness and will expose the motives of men’s hearts. The life of our heart is a hidden life…or so we think. But God knows all, sees all, understands all, and will forgive all if asked. And in doing so we’ll be given a new heart…exchanging our heart of stone for a heart of flesh.
Are you walking around with a hardened heart? When we’ve been hurt over and over again, our only recourse is to protect our heart…our inner person. We put up a wall of callousness and apathy so no one can hurt us again. It’s effective, but makes us appear uncaring and insensitive to others. It’s also really lonely within those walls…but we’re too afraid and distrustful to allow anyone in…so instead, we put on the mask of indifference.
But you may also be walking around with a hardened heart from sin. Everything is going great… you can make it on your own…you don’t need the Lord. But obstinately refusing God will only lead to destruction.
