Take example the person who fasts. In his fast he may perhaps abstain from many foods, yet he cannot abstain for one particular food, which he desires. What does such a person gain from his fast so long as he is weak and lacks the power to control himself at the point when he is being attached with the desire of food? Do we not say that if he abstains from this food in particular, he will be successful in his fast and in his spirituality? However, if he falls in this, then he has fallen in all. The Bible reminds us of this, saying: “For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all” (James 2.10). What is the meaning of this statement by the apostle? How should we understand it? You will understand by answering the following question: Do you love God, so that nothing can keep you away from Him? If you find anything at al, then this is the problem in your life; it is your point of weakness.
