As to the belief that Christ gave his life to save the world, it explains the real meaning of sacrifice: that no man in this world going towards the goal will escape from the test to which life will put him. And that test is sacrifice. At every step towards the final goal, the attainment, a greater and greater sacrifice will be demanded of him, until he arrives at a point where there is nothing, whether body, mind, action, thought, or feeling, that he keeps back from sacrifice for others. It is by this that man proves his realization of divine truth. In short, the Christ-ideal is the picture of the perfect man; and the explanation of what the perfect man is and what are his possibilities can be seen in the verse of the Bible, 'Be ye perfect even as your Father in heaven is perfect.'
