The psalmist has memorized God’s Word (Psalm 119:11) and he prays to God to teach him the word (Psalm 119:12). But he is not content with memorization and understanding. He must declare the law of God (Psalm 119:13). One commentator thinks this refers to speaking to himself God’s Word. Most commentators think this refers to telling others the judgments of God. Either way, the Word of God does not remain in his heart, but overflows into his speech. Jesus says that our speech reveals our hearts (Matthew 15:18-19). God’s Word has filled up the psalmist’s heart. He has stockpiled God’s Word. So God’s Word is what comes out of his mouth.
The psalmist is not declaring his opinion or his idea, but the very words of God. Our own thoughts are of little consequence. The question at the bottom of all questions is what does God think? That is why the declaration of God’s Word to those around us is essential. Our words are to reflect God’s statutes. His interpretation of events, actions, emotions, and thoughts is to be our interpretation of them. Too often we see things through our eyes instead of through God’s Word.
The world is often what shapes our words instead of God’s Word. The movies we watch and the songs we listen to mold our hearts so that we think and feel as the world does. If we find ourselves unable to converse easily about things like sin, salvation, redemption, Christ, the Church, grace, etc. then we should go back to verses 11-12 and begin internalizing God’s Word. If the language of the Bible is foreign to you then it has not taken root in your heart yet.
But often we know God’s Word and still refuse to declare it. We might refuse to declare God’s Word because we are cowards. We keep God’s Word in our hearts so no one will think the less of us or make fun of us. We want to be thought of as respectable and cool. Therefore we are quiet and God’s Word is left at our desk and never brought into the workplace, the dining room, the living room, the park, or the family reunion. We might refuse to declare God’s Word because we do not want to look “holier than thou.” This is a legitimate problem. But God does not give us the option of being silent. We must learn to declare God’s Word without being pompous or proud. There are probably other reasons we do not talk about God’s Word as we ought to.
