The truth is, the more intimately you know someone, the more clearly you will see their defects. That is just the way it is. That's why marriages fail, why children are abandoned, why friendships don't last. You may think you love someone, until you see the way they act when they are broke or under pressure or hungry, for God's sake. Love is something different. Love is the choice of someone to serve and be with someone, despite their dirty heart. Love is patient and kind, love is deliberate. Love is difficult. Love is pain and sacrifice, he is seeing darkness in another person and defying the urge to abandon the ship.
