There is a direct connection between the heart of man and the intelligence of the tongue. Proverbs 18:21 tells us that death and life are in the power of the tongue and they which love it shall eat the fruit thereof. We know that it’s from the abundance of the heart that the mouth speaks, according to Luke 6:45. That means what the tongue or mouth says comes from the heart. The intelligence of the tongue therefore comes from the heart. The tongue only utters the overflow of the heart. Evidently, your mouth and heart are connected or related. Therefore to develop the intelligence and articulate the coordination of the tongue, the heart must be inclined towards wisdom, in meditating on the things that pertain to life and godliness. A wholesome tongue is a tree of life which grows from the roots of a sound heart.
The heart is made up of what it meditates on consistently. Our meditation forms the content of our hearts, and that in turn forms the content of our vocabulary, for out of the abundance of the heart, the mouth speaks. Don’t meditate on whatever you don’t want your mouth to say. That’s why it’s important to meditate on the Word of God. Proverbs 4:20-22 tells us to give attention to the words of God, and incline our ears to God’s sayings; and let them not depart from our eyes, but keep them in the midst of our heart, for they are life to us when we find them and health to all our flesh. To build internal intelligence that makes for external intelligence, we must meditate on the Word daily. You will begin to use your tongue more discreetly and wisely as you feed your heart with the Word by meditating and acting on the Word. Let no corrupt communication flow out of your mouth, don’t let it! Make sure you maintain the cycle of wisdom, which is hearing wise words consistently, and speaking them consistently. Let your heart hear your mouth wisely, and the heart will feed your mouth wisely. That’s how to have the tongue of the learned; your ears are hearing the words of wisdom daily, morning by morning.
My Solid Front (Confession): In the Name of the Lord Jesus Christ, I declare that my tongue is a tree of life; I speak words of life and of grace, and my lips feed nations unto edification and fulfilment of destiny. Amen.
