"A man who is born again is careful of his own soul.
He tries not only to avoid sin - but also to avoid everything which may lead to it.
He is careful about the company he keeps.
He know that "bad company corrupts good morals" and that evil is more contagious than good, just as disease is more infectious than health.
He is careful about the use of his time; his chief desire is to spend it profitably.
He desires to live like a soldier in an enemy country - to wear his armor continually and to be prepared for temptation.
He is diligent to be a watchful, humble, prayerful man."

- J. C. Ryle
