“Keep your heart with all diligence.” Proverbs 4:23. What was Israel’s most prized possession? It was the temple – the special place where the worshiped God. The descendants of Levi were responsible for guarding this most sacred spot. They were to protect the sacred objects inside from being stolen or desecrated. In the New Testament we who believe in Christ are temples (I Corinthians 6:19-20). Our spiritual center, referred to in the Bible as the heart, contains valuable treasures as well: virtue, loyalty to God, trust, love, purity. How do we guard our hearts against evil? By meditating on God’s Word and confessing our sins. Be on guard against evil, or you’ll be influenced by it.
