In Mark's narrative (Mark 2:4), it is described that those carrying the paralytic made considerable effort to break through the roof (εξορυξαντες). This suggests that they removed the roofing materials, excavating the earth and dismantling the ceiling structures. The pallet on which the sick man was brought was likely lightweight, something the healed individual could carry, similar to felt, suitable for resting during their journey. Recognizing the faith of the individuals who brought the sick man, Jesus addressed him, saying, "Child, your sins are forgiven you." The Pharisees present considered this statement blasphemous, believing that only God could forgive sins. In response, Christ implied that healing a sick person is no less profound than offering forgiveness of sins. Thus, if they acknowledged His ability to heal, they should also recognize His authority to forgive.
To address any doubts the Pharisees might have held regarding the validity of His forgiveness declaration, Jesus instructed the healed man: "Arise, take up your bed, and go into your house." The immediate result of His command led the Pharisees to infer that His prior words, "Your sins are forgiven you," were likewise effective. The phrase "Son of man on earth" stands in contrast to the notion of God in heaven, as articulated by the Pharisees.
