But there is another phase of connection between these two points of the ideal character--if my spirit is to be holy and to preserve its holiness, it must be firm. That is to say, you can only get and keep purity by resistance. A man who has not learned to say 'No!'--who is not resolved that he _will_ take God's way in spite of every dog that can bay or bark at him, in spite of every silvery voice that woos him aside--will be a weak and a wretched man till he dies. In such a world as this, with such hearts as ours, weakness _is_ wickedness in the long run. Whoever lets himself be shaped and guided by anything lower than an inflexible will, fixed in obedience to God, will in the end be shaped into a deformity and guided to wreck and ruin. Dreams however rapturous, contemplations however devout, emotions however deep and sacred, make no man pure and good without hard effort, and that to a large extent in the direction of resistance. Righteousness is not a mere negative idea, and Scripture morality is something much deeper than prohibitions. But there is no law for us without prohibitions, and no righteousness without casting out evil that is strong in us, and fighting against evil that is attractive around us. Therefore we need firmness to guard holiness, to be the hard shell in which the rich fruit matures. We need a wholesome obstinacy in the right that will neither be bribed nor coaxed nor bullied, nor anyhow persuaded out of the road in which we know that we should walk. 'Add to your faith manly vigour.' Learn that an indispensable requisite of holiness is prescribed in that command, 'Whom resist, steadfast in the faith.' And remember that the ground of all successful resistance and the need for it are alike taught in that series of petitions, which makes a holy spirit the foundation of a constant spirit, and a constant spirit the guard of a holy spirit.
