I’ve often heard people, including Christians, say, “Well, what I have in my heart doesn’t really matter, it is what I say that’s important.” This isn’t true because the contents of your heart matter a great deal! Your words are the products of the contents of your heart.
The Amplified translation of the book of Proverbs 4:23 says, “Keep and guard your heart with all vigilance and above all that you guard, for out of it flow the spring of life.” This means you should set security watch at the gatepost of your heart to scrutinize the information that enters with the Word of God. This is why you need to take the Word of the Lord seriously.
You can’t confess the Word when you don’t have the Word in you, and you won’t get the Word into you by watching television, spending endless hours talking with your friends or wasting time with other irrelevant activities. You must study the Word of God, master it, learn it and live by it. This is so important because what you have in you is what will come out of your mouth and what comes out of your mouth is what will govern your life.
I exhort you today, just as the apostle Paul exhorted the Church at Colosse: “Let the word [spoken by] Christ (the Messiah) have its home [in your hearts and minds] and dwell in you in [all its] richness...” (Colossians 3:16 Amp). When you soak a sponge in water long enough till it becomes saturated, you’ll discover that water will ooze out of it at the slightest pressure. Likewise, be full of God’s Word so that when the devil tries to apply pressure on you, God’s Word will ooze out of you and he’ll flee from you. This won’t only get the devil off your back, it’ll also propel you on to a new and a higher realm of faith!
