Our talk is as important as our walk. The Bible counsels us of the value of being careful in how we speak. “Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.” – Ephesians 4:29. As children of God, we are not only expected to glorify God in how we do things but also in how speak or how we talk.
Be the mouthpiece of God. God said to Jeremiah, “If you utter what is precious, and not what is worthless, you shall be as my mouth.” – Jeremiah 15:19. God requires that as we follow Him, we also obey Him even in the manner of speaking. We are to give glory to God even in how we speak. We are to utter what is precious and not what is worthless. For how can we reflect God’s goodness, love, and grace if our speech does not show it? How can we be witnesses of God’s goodness if our speech is not enriched with His grace, peace, and love? As God’s children, walking with God means we become His mouthpiece. We should speak about God and His Word. We should speak the truth and not the lies. We should speak to encourage others and not to break their will. We should speak with truth and wisdom and not to please or tickle people’s ears. We should speak with humility and not with boastfulness. Oh, how good would it be if we would have mouth filter! Such a thing that could filter out every word we tend to speak and trash the words that are worthless. But that is not God’s way. We are to have our own will and control in our speech to speak kindly and truthfully. Sometimes, though, we give in to the temptation of speaking worthless words which are spoken and meant to lie, to insult, to hurt, to demean, to put down, and to criticize unjustly. These words are not pleasing to God and does not glorify Him.
What our mouth speaks is what our heart thinks. What we say is what is actually in our heart. The words we utter are the very thoughts of our heart. We cannot say that we do not mean it. We cannot say that it is just a slip of the tongue. It is a slip of the tongue because it has been in the heart for quite a while. The mouth just blurted it out. Jesus said, “You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. I tell you, on the day of judgment people will give account for every careless word they speak, for by your words you will be justified, and by your words you will be condemned.”– Matthew 12:34-37. “But what comes out of the mouth proceeds from the heart, and this defiles a person.” – Matthew 15:18. Does the Bible lie? Does the Word of God lie when it says that what is in our heart is what we will speak out? God’s Word is perfect and true. It always speaks the truth. Indeed, our words reflect the condition of our heart. Pause and reflect for a while. Look back for instances in your life when you have uttered words of praise and admiration or of anger and dislike. Isn’t it because those were the very thoughts in your heart? King David prayed this, “Set a guard, O Lord, over my mouth; keep watch over the door of my lips!” – Psalm 141:3. King David understands how easy it is for a human lip to err, lie, brag, and speak unkindly. We need the hand of God to tame our tongue and renew us inwardly so we could utter precious words. We could not speak this kind of words or become the mouthpiece of God if our heart is not right with God. It all starts in the heart.
