Family is important. Very important. But we go too far if we maintain that "Blood is thicker than water." When Jesus was asked to acknowledge his mother and brothers who had come to see him, he seized the opportunity to establish heaven's hierarchy: "Whosoever shall do the will of God, the same is my brother, and my sister, and my mother." In other words, when determining ultimate loyalties, the water of baptism always trumps the blood of physical descent. Or, to put it more simply, "Water is thicker than blood."
