The Man on the Mat by Hazel Scrimshire
The man on the mat was sad that he could not walk. But then his friends brought him to see Jesus, and Jesus did something amazing! It turned out that not being able to walk was not the only problem the man had - he also needed to have his sins forgiven. Not only was Jesus able to make him walk again, he also forgave his sins.
This story can be found in the Bible in Mark 2:1-12.
