“Why do you reason because you have no bread? Do you not yet perceive nor understand? Is your heart still hardened?” ~ Mark 8:17
If Jesus’ disciples could let their hearts get hardened then I believe that His disciples can let their hearts get hardened today. As disciples of Jesus we must be on guard that we don’t let our hearts get hardened or desensitized.
What does it mean to be desensitized? It means that things that used to bother us or grieve us or vex us no longer do. Perhaps things on TV, or music, or things we allow ourselves to participate in that once bothered us now no longer bother us as much. It’s not that those things aren’t as bad as they used to be, the problem is that we have become desensitized to them. That’s a dangerous place to be.
So just how do we get our hearts sensitive again? First, ask God to help you to have a heart that’s in tune with His heart. One that loves what He loves and hates what He hates. Second, stop allowing things into your life that are contrary to His Word and will for you. Things that are offensive to Him will harden your heart.
If you want to live in a place where your heart can clearly hear God’s voice you’ll have to be diligent about what you allow into your life. As Proverbs 4:23 says, “Keep your heart with all diligence!”
