Today many modern Christian groups question the necessity of fasting prayers in their spiritual walk. For many such, their anointing of the Holy Spirit is only the ecstasy experienced in their praise and worship sessions, lasting a couple of hours or more. Many are not concerned about their time before and after such sessions. The phenomena of the anointing of the Holy Spirit is not merely a short worship session experience but a continuous 24/7 presence. Those who are anointed and led by the Holy Spirit should always be aware that Satan is at their heels to destroy their anointing. He hates them as they are away from him, and lead others away from him too! So he wants to destroy the anointed people of God. That is why Peter warns us to be vigilant, “because your adversary the devil walks about like a roaring lion, seeking whom he may devour.” (1 Peter 5:8)
Jesus forewarned his followers about the adversary Satan and gave them a mighty weapon to defeat him – “However, this kind does not go out except by prayer and fasting.” (Matthew 17:21) He proved that by his own life, defeating Satan by fasting and prayer. Thus Jesus established fasting prayer as the divine weapon for the children of God, to defeat Satan, in their spiritual walk.
It is true without fasting a prayer we will be spiritually weak.
perfect fasting is a weapon to defeat Satan.
