Most Christians want to be pure and live a life that is honoring to God. We want our minds to be clean and our hearts to be right; but our hearts are “deceitful above all things, and desperately wicked: who can know it?” (Jeremiah 17:9) If we can’t even understand our own hearts, how can we possibly keep them clean?
The answer is, we can’t – at least, not by ourselves. We need the Holy Spirit guiding us and helping us. According to Psalms 19:14, “The words of [our] mouths and the meditation of [our] hearts [should] be acceptable in [God’s] sight.” But, the world we live in is full of junk! How can we keep our hearts and minds clean? We need a filter. The Bible gives us a perfect filter. Philippians 4:8 says,
“Finally, brethren, whatever things are true, whatever things are honorable, whatever thing are pure, whatever things are lovely, whatever things are just, whatever things are commendable, whatever things have a good report, if there is any excellence, and if there is any praise, think about these things.”
