Fasting is a sign of love for God and His commandments by humans. It becomes a powerful means to deepen the love of God in the heart of man.
This is how Abba Benjamin, Bishop of Menoufia, told us in his article Fasting and purity explaining the relationship between fasting and purity. Through fasting, the body is purified of instincts and materialistic tendencies. Saints added praises and spiritual practices to fasting in order to receive the Holy Spirit.
The Apostle Paul says, I oppress my body and enslave it . Repression means submission to the leadership of God through the work of the Holy Spirit. The Apostle Paul also says: If you live according to the flesh, you will die
Sin comes from the inside the good man from the treasure of his good heart brings out good deeds and the wicked man from the treasure of his evil heart brings out evils Therefore, Christians should sustain spiritual jihad and fasting that purifies our hearts.
