When God Hears Our Prayer.
When we prepare to pray, we must first make peace with everyone to whom we have done evil, and even with those who have anything against us, and after that, with reverence and attention, stand for prayer. During prayer we must direct our mind so that it does not think about anything else, so that our heart wishes only one thing: to pray better and please God.
If we pray without making peace with our neighbors, if we pray hurriedly, if we talk or laugh during prayer, then our prayer will not be pleasing to God. God will not hear such a prayer, and He might even punish us.
For more diligent and intense prayer, and for a good pious life, fasting has been established.
The time of fasting, or lent, is the period when we must think more about God, about our sins before God, when we must pray more, repent, not get upset or hurt anyone, but rather, help everyone, read God’s law, and so on. And to make it easier to fulfill all this we must first of all eat less — not eat any meat, eggs, or milk, that is, animal and dairy products, but eat only “Lenten” food, that is, from plants: bread, vegetables, fruit, and fish (if allowed). We fast because the rich foods from animal and dairy products call forth a desire not to pray, but to sleep, or to act foolishly. When we develop the habit of not giving in to our desires for more or rich foods it makes it easier to fight against sin.
