Luke 8:46

I perceive that virtue - Δυναμιν , Divine or miraculous power. This Divine emanation did not proceed always from Christ, as necessarily as odours do from plants, for then all who touched him must have been equally partakers of it. Of the many that touched him, this woman and none else received this Divine virtue; and why? Because she came in faith. Faith alone attracts and receives the energetic influence of God at all times. There would be more miracles, at least of spiritual healing, were there more faith among those who are called believers.
