But His commandment is exceeding broad; becomes broader year by year with every revelation of science; and we had need gird up the loins of our mind to keep pace with this current revelation. We shall be at pains, too, to keep ourselves in that attitude of expectant attention wherein we shall be enabled to perceive the unity and continuity of this revelation with that of the written Word of God. For perhaps it is only as we are able to receive the two, and harmonise the two in a willing and obedient heart, that we shall enter on the heritage of glad and holy living which is the will of God for us. Let us, for example, consider, in the light of current scientific thought, the processes and the methods of this second birth, which, according to M. Monod, the child claims at the hands of his parents. “Train up a child in the way he should go, and when he is old he will not depart from it,” is not only a pledge, but is a statement of a result arrived at by deductive processes. The writer had great opportunities for collecting data; he had watched many children grow up, and his experience taught him to divide them into two classes--the well-brought up, who turned out well; and the ill-brought up, who turned out ill. No doubt, then, as now, there were startling exceptions, and--the exception proves the rule. But, here as elsewhere, the promises and threatenings of the Bible will bear the searching light of inductive processes. We may ask, Why should this be so? and not content ourselves with a general answer, that this is natural and right: we may search until we discover that this result is inevitable, and no other result conceivable (except for alien influences), and our obedience will be in exact proportion to our perception of the inevitableness of the law. The vast sum of what we understand by heredity is not to be taken into account in the consideration of this second birth; by the first natural birth it is, that “his father and mother, his grandfather and grandmother, are latent or declare themselves in the child; and it is on the lines thus laid down in his nature that his development will proceed. It is not by virtue of education so much as by virtue of inheritance that he is brave or timid, generous or selfish, prudent or reckless, boastful or modest, quick or placid in temper; the ground tone of his character is original in him, and it colours all the subsequently formed emotions and their sympathetic ideas.... The influence of systematic culture upon any one is no doubt great, but that which determines the limit, and even in some degree the nature of the effects of culture, that which forms the foundations upon which all the modifications of art must rest, is the inherited nature.”
