Faith is a word of action. Consider the following passages:
“Seeing their faith”
When Jesus was in Capernaum, the crowds so pressed him that some who sought his presence could not gain access. Four men brought a lame friend. They climbed to the rooftop of the house wherein Christ was teaching and lowered their companion through the ceiling.
Significantly, Mark says: “And Jesus seeing their faith said unto the sick of the palsy, Son, your sins are forgiven” (Mk. 2:5).
What did Christ see? He literally saw the action of these men (including the sick one who obviously endorsed the activity). But the action is called faith.
In a similar vein, James challenged: “Show me your faith apart from your works, and I by my works will show you my faith” (Jas. 2:18).
