Many are overcome, because they allow their zeal to grow cold, and run off in self-flattery. Others, on the contrary, become so alarmed when they do not find in themselves, the strength they wish, that they get confused, and give up the struggle altogether. What then is to be done? Arouse yourself to meditate, as much upon the promises of God, which ought to serve as ladders to raise us up to Heaven, and make us despise this transitory and fading life, as upon the threatening, which may well induce us to fear his judgments. When you do not feel your heart moved as it ought to be, have recourse, as to a special remedy, to diligently seeking the aid of him without whom we can do nothing. In the meantime, strive to your utmost, blaming coldness and weakness, until you can perceive that there is some amendment. And in regard to this, great caution is required so as to hold a middle course, namely, to groan unceasingly, and even to woo yourself to sadness and dissatisfaction with your condition, and to such a sense of sin and misery as that you may have no rest; without at the same time, doubting that God in due time will strengthen you according to your need, although this may not appear at once.
