Text: Prov. 4:20-23. How do you keep (guard) your heart with all diligence as we are told to do in our text? First of all, you need to walk in the peace of God (Phil. 4:6-7). God wants you to prosper and be in good health even as your soul prospers. God works from the inside (your heart) out. When you’re not in peace, your heart is vulnerable. We are NOT to worry, but through prayer with thanksgiving, we are to let our requests be made known to God. Keep in a focused place. A “keep” is a fortification at a strategic place. When you keep your heart, the devil can’t get in. How do you take care of worry? First Peter 5:7 tells you to cast your care on Him, because He cares for you. Don’t try to be stronger than your cares, but start praising Him, replacing the worry with thanksgiving. The result? Peace. Pastor Dale tells about Terry Law’s experience with extreme cares upon the death of his wife and children. When Terry gave his sacrifice of praise, he entered into God’s peace. Keep your mind stayed on God (Is. 26:3), and He will keep your heart in perfect peace. Meditate on Him and be still. Delight in Him, and He will give you the desires of your heart (Ps. 37:4-7). Stay in God’s Word and presence until you get His peace.
