This is a quote of a quote from Jim’s Blog:
Some without fulfilling the commandments think that they possess true faith. Others fulfill the commandments and then expect the kingdom as a reward due to them, Both are mistaken, A master is under no obligation to reward his slaves; on the other hand, those who do not serve him well are not given their freedom.
St. Mark the Ascetic, â€œOn Those who Think that They are Made Righteous by Works: Two Hundred and Twenty-Six Textsâ€ 18-19 in the Philokalia, Vol. 1, p. 126. 146
Edit 2004.12.01: I agree with this statement and think it is well put and to the point. I may read more of this Mark the Aescetic’s works (linked above) when I have time.
