"He that hath ears to hear, let him hear" repeats the invitation to listen carefully, but with an added emphasis on the importance of responsiveness. To hear God's voice means not only to listen but also to act upon what we hear. Jesus urges us to take His teachings to heart, to be receptive to His guidance, and to allow His truth to shape our actions. Spiritual hearing involves attentiveness and willingness to follow God's direction, rather than hearing and ignoring. As we grow in our ability to hear and understand God's Word, we also grow in our ability to apply it in our lives, leading to deeper wisdom and understanding.
