Listening to expositions by a speaker who has had the thrill of genuine experience is a blessing. The speaker’s face will blossom with joy, their eyes will shed tears of exhilaration at the very contemplation of the Lord’s glory. Listeners will easily catch that inspiration and experience the joy themselves as tears stream down their eyes. When an infant smiles, everyone around the infant also smiles in unison. So too the words of those who are saturated with devotion to God will saturate the hearts of the listeners too. Through that process of listening, a dirt-laden heart will be transformed into a clean and illumined heart which shines with genuine light and love. To the foul odours of sense-pursuits, keenness to listen to the glories of God is a valuable disinfectant, besides being in itself so full of sweet fragrance. Listening will effectively cleanse your heart.
