Let the wise hear and increase in learning, and the one who understands obtain guidance. Proverbs 1:5 (ESV)
As believers, what we hear is very important. We are to only listen for what is good, pure, of life, and of God. It is not enough that we keep what comes out of our mouth as holy.
Listening to lies, coarse talking, and gossip cause us to meditate on things that are not holy. Our chief aim is to stay away from such things.
As we serve the Lord, let us keep our ears away from what is not holy, so that we will be open to hear the voice of God.
“Christians have forgotten that the ministry of listening has been committed to them by Him who is Himself the great listener and whose work they shall share. We should listen with the ears of God that we may speak the Word of God.” - Dietrich Bonhoeffer
