Jesus, James and
John arrived at
Peter's house and
was met by Peter's
wife with the news
that her mother
was sick.
"And forthwith,
when they were
come out
of the synagogue, they enterd into the house
of Simon and Andrew, with James and John.
But Simon's wife's mother lay sick of a fever,
and anon they tell him of her. And he came
and took her by the hand, and lifted her up,
and immediately the fever left her, and she
ministered unto them" Mark 1:29-31
Here we see that He didn't even pray but
acted on His authority by taking her hand
and lifting her up causing her to become well.
Faith is an act. We can learn from this woman
that when she responded to Jesus it caused her
to receive her healing.
