There was no question about it in her mind, nor should there be in ours. She touched Jesus with complete faith and purpose, knowing that she would get what she needed. See vs. 30, 32. The result was immediate healing. She knew she was healed, and this comes first.
Faith comes before receiving.
Knowing comes before manifestation, at least in most cases. Get unshakable faith by following the example of this woman. These were magnified to herself and to Jesus by her confession and single mindedness. She testified about what God had done for her. Her faith is a legacy that has come down to even us, as we study her life, receive from God.
