Many people were affected by a recent water scare here in Western New York. There was an issue with the water supply being unsafe to drink. Some boiled water for drinking while others turned to bottled water or filled containers in a neighboring town that wasn’t affected.
It’s interesting to see the widespread impact that occurs when a water source gets contaminated. It only takes a little bit, but the whole supply becomes virtually worthless for sustaining life. The same is true of our hearts. An impure heart leads to impure actions:
But what comes out of the mouth proceeds from the heart, and this defiles a person. For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. Matthew 15:18-19 (ESV)
Our hearts are evil and impure through and through, and the impact is just as far-reaching as that tainted water supply. Evil flows from our unclean hearts, manifesting itself in our words and actions every day. On our own, we are powerless to change it.
King David once realized that his heart was impure and corrupt. He recorded the agony and pain he felt because of this, but he also saw hope for change:
Create in me a clean heart, O God, and renew a right spirit within me.
Psalm 51:10 (ESV)
Like us, David could not change his heart on his own, so he cried out to the only one that could: his God. Jesus has come to make us pure in heart. He alone can do it, and all we need to do is trust in Him.
