This particular healing account has two main points. One point is the miraculous healing of the lepers
and the other point is the gratitude of the Samaritan.
The ability to see is an important part of this story. Saint Luke reports that Jesus was moved to heal all 10 after he saw them, which suggests something more than just physical sight. Jesus’ vision enabled him not only to be aware of their presence, but also to grasp their predicament and to empathize with their sufferings to the point that he acted to help them.
