Sight, taste, touch, pressure, itch, thermoception (sense of hot and cold), sound, smell, proprioception (sense of where your body parts are), tension, nociception (sense of pain), equilibrioception (sense of balance), stretch, chemoreception (sense that it is time to vomit), thirst, hunger, magnetoception, and time: none of these declare or make present the body and blood of Christ Jesus in His Supper, but they are all subject to His benefits.
God does not deal with man apart from reason and senses, but has endowed man with these so that He might bestow His grace by way of the same form He takes in His own Son, Christ Jesus. For the same reason, He uses preaching and sacraments to visit His people.
Through these the crucified and risen Christ is conveyed in full, when and where it pleases the Creator to breathe His Word and Spirit into the ears and hearts of the hearers. They, in turn, are called disciples, because they do not indulge themselves according to the flesh, but are driven (disciplined) to seek things above.
They cannot do otherwise, because they have died to sin. They are reckoned not according to what the eyes see, but according to what the Word says.
