The second element in the analysis of the true Christian life is--"increasing in the knowledge of God." The figure of the tree is probably continued here. If it fruits, its girth will increase, its branches will spread, its top will mount, and next year its shadow on the grass will cover a larger circle. Some would take the "knowledge" here as the instrument or means of growth, and would render "increasing by the knowledge of God," supposing that the knowledge is represented as the rain or the sunshine which minister to the growth of the plant. But perhaps it is better to keep to the idea conveyed by the common rendering, which regards the words "in knowledge" as the specification of that region in which the growth enjoined is to be realized. So here we have the converse of the relation between work and knowledge which we met in the earlier part of the chapter. There, knowledge led to a worthy walk; here, fruitfulness in good works leads to, or at all events is accompanied with, an increased knowledge. And both are true. These two work on each other a reciprocal increase. All true knowledge which is not mere empty notions, naturally tends to influence action, and all true action naturally tends to confirm the knowledge from which it proceeds. Obedience gives insight: "If any man wills to do My will, he shall know of the doctrine." If I am faithful up to the limits of my present knowledge, and have brought it all to bear on character and conduct, I shall find that in the effort to make my every thought a deed, there have fallen from my eyes as it were scales, and I see some things clearly which were faint and doubtful before. Moral truth becomes dim to a bad man. Religious truth grows bright to a good one, and whosoever strives to bring all his creed into practice, and all his practice under the guidance of his creed, will find that the path of obedience is the path of growing light. Then comes the third element in this resolution of the Christian character into its component parts--"strengthened with all power, according to the might of His glory, unto all patience and longsuffering with joyfulness." Knowing and doing are not the whole of life: there are sorrow and suffering too.
