True healing means drawing the circle of our being larger and becoming more inclusive, more capable of loving. In this sense, healing is not for the sick alone, but for all humankind.
Faith is not a once-done act, but a continuous gaze of the heart at the Triune God. Believing, then, is directing the hearts' attention to Jesus. It is lifting the mind to 'behold the Lamb of God,' and never ceasing that beholding for the rest of our lives.
