His Grace Abba Benjamin, Bishop of Menofia, wrote in his article prayer in the words of the holy fathers about the importance of prayer as explained by fathers of the church. Among their sayings the patience in prayer generates stability in front of the wars of prayer which means that prayers helps human to overcome spiritual wars that aims to stop man from continue praying. Moreover, it can lead man to a life of joy, thanks giving and peace.
Prayer also gives life and power to al spiritual works. This applies to repentance and fasting. It is a mean of love that strengthens the bond between man and God. Such relationship helps man to get rid of all evil lusts and anger.
