We have learned, and are learning constantly in every direction, that our happiness is involved in the happiness of other people. The world is haunted to-day and I thank God that it is with the thought of the unhappiness, the misery, of men. What does it mean? It means that men have developed so on their sympathetic side that they cannot be happy themselves while the world is unhappy. So you see that this self- development, which I placed as the chief thing at the outset in the meaning of life, carries with it the necessity on the part of those who are developed, of doing everything they can to develop and lift up everybody else; so that making the most of yourself means making the most of everybody else. And now, if I turn for a moment to that other point, merely to distinguish it by itself, although I have been dealing with it all the while, the end and aim of life once more is to be happy. I am perfectly well aware that the old Puritan theology has taught otherwise, so far as this life is concerned. I was brought up with the feeling that, if I wanted to do anything, the chances were it was wrong, that it was a good deal more likely to be in the way of virtue if it was something that was disagreeable to me. And yet, curiously enough, this old Puritan theology invented and held up before men, as a lure to lead them to virtue, the most tremendous bribe that ever entered into the imaginations of men, eternal felicity on the one hand, and eternal woe on the other. So that it conceded the very thing that it seemed to deny, that men naturally and necessarily sought happiness, and could not possibly do otherwise. And so we learn to live, to think, to serve others. We are beginning to learn also that this desire for happiness is natural, is necessary, is right. If a man is not happy, you may be sure there is something wrong. If there is pain in the body, it means disease, difficulty, obstruction, something out of the way. It means that God's laws are not perfectly kept. If there is pain up in the mental realm, pain in the moral realm, pain in the spiritual realm, it means always something wrong. Man ought to be happy. He ought to seek happiness as the great end and outcome of human life. And we are learning, as the natural and necessary result of our experiences in knowing and in serving, that just in so far as we know the laws of God, just in so far as we obey the laws of God, just in so far as we help others to know and obey, just in so far there comes into our lives the blessedness of the blessed God.
