"You sow a thought and you reap a deed. You sow a deed and you reap a habit. You sow a habit and you reap a character. You sow a character and you reap a destiny."

"Every time we allow our mind to harbor a grudge, nurse a grievance, entertain an impure fancy, wallow in self-pity, we are sowing to the flesh. Every time we linger in bad company whose insidious influence we know we cannot resist, every time we lie in bed when we ought to be up and praying, every time we read pornographic literature, every time we take a risk that strains our self-control, we are sowing, sowing, sowing to the flesh." – John Stott
