For it is a pleasant thing if thou keep them within thee; they shall withal be fitted in thy lips. That thy trust may be in the LORD, I have made known to thee this day, even to thee.
We are told here that it is a pleasant, or delightful, thing for us when we keep the Word within us. To keep means to guard, to protect, to attend, and to hedge about. That is what we are supposed to do with the Word of the Lord. We are told that keeping His Word within us is a delightful thing.
It literally does make you feel better to have the living Word of God inside your heart. The passage goes on to say that they, the Word, shall be fitted in our lips. The word fitted means to stand erect and to confirm. What is on your lips? Complaining? Negative words? What is within your heart will confirm what is on your lips. That is why we cannot change our confession until we begin to place the Word of God within our hearts. (Mark 7:21 For from within, out of the heart of men, proceed evil thoughts)
Finally, verse 19 says because we guard and keep His Word in our hearts that it will cause us to trust in the Lord. When we take the time to read, study, and mediate on what our Father has spoken to us, we find ourselves getting to know Him more. And with more intimacy comes more trust.
You realize that He truly is your Refuge. He is the place you can run to when the chaos or even the mundane are around you. Today, Jesus is speaking to you through His Word. Have you taken the time to see what it is He has to say? You will grow in love, faith, and trust as you daily partake of His Word.
