We see the face of God daily, easily recognizable in a spectacular sunset or in a child's smile. And it also exists in less attractive presentations. Can we accept seeing God in the person of our "enemy"? If we can't, we are doomed to propagating lives of hatred and revenge. Only when we see the face of God in everyone and in all things will we be at peace within ourselves and, more importantly, enable peace to exist throughout the world.
Every person has a share in this world and a share in the world to come. We understand the concept of a share in the world to come, but what does it mean having a share in this world? Open your hearts. Having a share in this world means I know exactly what I have to do in this world. This is a very high level. If I know that if I don't do it, it just won't happen. Then I've just got to do it. This is my share in this world.
