(Proverbs 15:7 KJV) The lips of the wise disperse knowledge: but the heart of the foolish doeth not so.
Wisdom speaks from the “heart” (3820). This is the inner man. This is character and common sense. Where does this inner being come from?
Part is from your training. When dealing with problem children we often note how the nut does not fall far from the tree. Parents, family and even kindergarten teachers lay a foundation of right and wrong that is hard to change in later years. I have heard that the Catholic church says to give them a child until he is five and he is theirs for the rest of his life. Early training is vital.
But it does not stop there. If it did there would be no hope for most of us. We would be locked into our fates from an early age. One reason I do not like to play Monopoly is that I know who is going to win after about 30 minutes of the game. The die is cast and only a freakish amount of luck can change it. God’s grace, the power of the blood and the work of the Holy Spirit change that.
So? If you have wisdom, dispense it. If you don’t, seek revival. After you get your heart right, speak from the heart.
