For what profit is it to a man if he gains the whole world, and yet loses his own soul? Or what can one give in exchange for his soul?... Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and there are many who enter through it. But the gate is small and the road is narrow which leads to life, and there are few who find it... (Matthew 16:26; Matthew 7:13-14)
