The following is taken from Wounded by Love: the Life and Wisdom of Elder Porphyrios
You don’t become holy by fighting evil. Let evil be. Look towards Christ and that will save you. What makes a person saintly is love – the adoration of Christ which cannot be expressed, which is beyond expression, which is beyond… And such a person attempts to undertake ascetic exercises and to do things to cause himself to suffer for the love of God.
No monk became holy without ascetic exercises. No one can ascend to spirituality without exercising himself. These things must be done. Ascetic exercises are such things as prostrations, vigils and so on, but done without force. All are done with joy. What is important is not the prostrations we will make or the prayers, but the act of self-giving, the passionate love for Christ and for spiritual things. There are many people who do these things, not for God, but for the sake of exercise, in order to reap physical benefit. But spiritual people do them in order to reap spiritual benefit; they do them for God. At the same time, however, the body is greatly benefited and doesn’t fall ill. Many good things flow from them.
