Renunciation is not a wholly passive thing; it is not a mere suspicion of all that is joyful, a dull abnegation of happiness. It is not that self-sacrifice means a frame of mind too despondent to enjoy, so fearful of every kind of pleasure that it has not the heart to take part in it. It is rather a vigorous discrimination between pleasure and joy, an austerity which is not deceived by selfish, obvious, apparent pleasure, but sees what sort of pleasure is innocent, natural, social, and what sort of pleasure is corroding, barren, and unreal. In the Christianity of the Gospel there is very little trace of asceticism. The delight in life is clearly indicated, and the only sort of self-denial that is taught is the self-denial that ends in simplicity of life, and in the joyful and courageous shouldering of inevitable burdens. Self-denial was not to be practised in a spiritless and timid way, but rather as a man accepts the fatigues and dangers of an expedition, in a vigorous and adventurous mood. One does not think of the men who go on some Arctic exploration, with all the restrictions of diet that they have to practise, all the uncomfortable rules of life they have to obey, as renouncing the joys of life; they do so naturally, in order that they may follow a livelier inspiration. It is clear from the accounts of primitive Christians that they impressed their heathen neighbours not as timid, anxious, and despondent people, but as men and women with some secret overflowing sense of joy and energy, and with a curious radiance and brightness about them which was not an affected pose, but the redundant happiness of those who have some glad knowledge in heart and mind which they cannot repress.
