Howbeit this kind goeth not out but by prayer and fasting. Matthew 17:21
Casting out devils is one of the signs that follows the believer and fasting empowers the believer to do that. “And these signs shall follow them that believe; in my name shall they cast out devils…” (Mark 16:17). Satan and all his demons are the wicked forces behind all the troubles and afflictions tormenting people. God does not afflict and torment people. “Yea, the LORD shall give that which is good; and our land shall yield her increase” (Psalm 85:12). If it is not good, God did not give it. “Every good gift and every perfect gift is from above, and cometh down from the father of lights, with whom is no variableness, neither shadow of turning.” (James 1:17). It is therefore wrong to assume that any bad thing that happens to you can come from God. God only does good things.
God will not change from his good nature to become bad. “Jesus Christ the same yesterday, and today and for ever” (Hebrews 13:8). God only give good gifts to people. “For the Lord God is a sun and a shield: the Lord will give grace and glory: no good thing will he withhold from them that walk uprightly.” (Psalm 84:11).
If it is not good, then it is not from God. It is Satan that brings bad. Fight that devil with prayer and fasting. Fasting is a key that delivers good things into people’s hand. You cannot engage this key and come out empty.
Prayer focus: Father, nothing is greater than your power. As I seek you in prayer and fasting break and terminate every chain of bondage around my life and destiny.
