If we fervently desire holiness, the Holy Spirit at the outset gives the soul a full and conscious taste of God’s sweetness, so that the intellect will know exactly of what the final reward of the spiritual life consists.
Holiness is not simply righteousness, for which the righteous are rewarded with blessedness in the Kingdom of God; rather, it is such a height of righteousness that people are so filled with the grace of God that it flows from them even upon those who associate with them. Great is their blessedness, which proceeds from their direct contemplation of the glory of God. Being filled also with love for men, which proceeds from love of God, they are responsive to men's needs, and at their entreaties they act as mediators and intercessors for them before God.
What is it that commends our own life? Is it miracles, or is it a life scrupulously and uprightly lived? It is rather from the latter that miracles arise, and to that they tend. For he that lives a worthy life, draws this grace upon himself; and whosoever receives such graces receives them that he may help others to amend their lives. For even Christ wrought miracles that He might the more be accepted as worthy of belief, and so might the more attract men to Himself, and by this means bring sanctity into their lives.
