Our soul, as a spiritual, active being, cannot remain idle; it either does good or evil, one of the two; either wheat grows in it or tares. But as every good comes from God, and as the means of obtaining every good from God is prayer, those who pray fervently, sincerely, from the depths of their hearts, obtain from the Lord grace to do good, and, before all, the grace of faith; whilst those who do not pray, naturally remain without these spiritual gifts, voluntarily depriving themselves of them by their own negligence and spiritual coldness.

St. John of Kronstadt
