If a person pushes himself to attain prayer alone...

If a person pushes himself to attain prayer alone, when he has none, in order to attain its grace, without striving earnestly for meekness and humility and charity and all the other commandments of the Lord, neither taking pains nor struggling and battling to succeed in these as far as his choice and free will go, he may at times be given a grace of prayer with some degree of repose and pleasure from the Spirit according as he asks. But he has the same traits he had before. He has no meekness, because he did not seek it with effort and he did not prepare himself beforehand to become meek. He has no humility, since he did not ask for it and did not push himself to have it. He has no charity toward all men, because he was not concerned with it and did not strive for it in his asking for the gift of prayer. And in doing his work, he has no faith or trust in God, since he did not know that he was without it. And he did not take the pains to seek from the Lord for himself to have a firm faith and an authentic trust.

St. Macarius the Great,
