Avoid, too, an illusion into which beginners in the spiritual life frequently fall. Having read in certain books of the ineffable consolations of the Holy Spirit, and the joys of God's service, they persuade themselves that the path of virtue is filled with delights, and therefore, instead of entering it armed to meet their enemies, they set out as if for a festival. Truly the love of God is full of sweetness, but the way which leads to it contains much that is bitter, for self-love must first be conquered, and there is nothing harder to nature than to fight against it and all that it claims.
