Jesus was speaking in a crowded house when some men brought their sick friend on a bed through the roof to be healed. As the house was too crowded, they lowered the man on his bed through the hole in the roof for Jesus to see him. Jesus, pleased by their faith, told the sick man to stand up and walk, and immediately healed him so that he could even jump. The man then ran home praising God. The story comes from Mark 2:1-12.
