Every thing around us and every thing within us makes us conscious of limitation and dependence. We know that our own existence is not self-originated or self-sustained. We have the sense of an immanent all-pervading Life which sustains and conditions our life. We have the sentiment of an overshadowing Power and Presence which compasses us behind and before, and lays its hand upon us, and we are constrained to bow in reverence and awe before that Power which controls our destiny. With the sense of dependence is associated the feeling of obligation to conform our conduct to the will of this Supreme Being, and to subordinate the ruling purpose of our life to the Divine purpose of creation so far as that purpose can be known. There is also more or less loyalty of soul to what is just and true, a natural and constitutional sympathy of reason with the law of God--"it delights in that law," and "consents that it is good." Finally, there is the consciousness of some community of nature between God and man, and some living susceptibility to the influences and inspirations of the higher world which authorizes the belief that there may be a communion of thought, a relation of conscience, and an approach of affection between the Divine and human that shall purify and elevate our nature, and lift us up into a resemblance to God. The bearing of all that we have just said on the necessity of prayer will have already suggested itself to the reader. The feeling of dependence, the sense of feebleness will prompt man to pray. Man is not sufficient for himself. He is not fit to be his own all in all. He has not resources within himself to supply his own spiritual wants. He needs some external succor, some support to the will, some inspiration from without. And he can become a strong man and a noble man only by aspiring and striving after something beyond and above himself-- "Unless above himself he can Erect himself, how mean a thing is man!" When his affections and cares and thoughts all centre upon himself, his soul shrivels down to a dreary selfishness, and becomes a dry microscopic point, or else a mass of putrid sensuality. Man needs a lofty object above himself, after which he may aspire and upon which he may lay hold and lift himself into a nobler form of life. That lofty object is the ideal of a _perfect, noble human character_. "The formation of noble human character," says Mr. Murphy, "is the highest work that man or, so far as we know, that God can be engaged in."[418] The thoughtful mind recognizes that there is a purpose to be fulfilled in life which is nobler than mere enjoyment. Who has dared to say that our highest duty is to be happy? But every one must feel that it is our highest duty to form a nobler character and let the happiness take care of itself.
