There is a modern school which protests against the doctrine of man's inability as the heartless fiction of a past theology. While some forms of that dogma, to any one who knows man, are incapable of defence, there are others which, to any one who knows Nature, are incapable of denial. Those who oppose it, in their jealousy for humanity, credit the organism with the properties of Environment. All true theology, on the other hand, has remained loyal to at least the root-idea in this truth. The New Testament is nowhere more impressive than where it insists on the fact of man's dependence. In its view the first step in religion is for man to feel his helplessness. Christ's first beatitude is to the poor in spirit. The condition of entrance into the spiritual kingdom is to possess the child-spirit--that state of mind combining at once the profoundest helplessness with the most artless feeling of dependence. Substantially the same idea underlies the countless passages in which Christ affirms that He has not come to call the righteous, but sinners to repentance. And in that farewell discourse into which the Great Teacher poured the most burning convictions of His life, He gives to this doctrine an ever increasing emphasis. No words could be more solemn or arresting than the sentence in the last great allegory devoted to this theme, "As the branch cannot bear fruit of itself except it abide in the vine, no more can ye except ye abide in Me." The word here, it will be observed again, is _cannot_. It is the imperative of natural law. Fruit-bearing without Christ is not an improbability, but an impossibility. As well expect the natural fruit to flourish without air and heat, without soil and sunshine. How thoroughly also Paul grasped this truth is apparent from a hundred pregnant passages in which he echoes his Master's teaching. To him life was hid with Christ in God. And that he embraced this not as a theory but as an experimental truth we gather from his constant confession, "When I am weak, then am I strong." This leads by a natural transition to the second of the three points we are seeking to illustrate. We have seen that the organism contains within itself only one half of what is essential to life. We have next to observe, as the complement of this, how the second half is contained in the Environment.
