GODS RELATION TO POWERS

1. God is seated above all principality,  power. He is the Lord of Hosts, which means the lord of all spiritual beings, and so they(all spiritual things) owe their power to Him. All Angels, be they fallen or not, have to bow in the presence of God.
2. Power is represented in the scripture as wine. Wine taken uncontrollably has properties of overcoming the control of the drinker. So does spiritual power, if taken without reason, which is what the rulers of this world do by theft. This is what they(the thieves) come to steal. 
3. Servants of God receive power as the need arises, seasonally. This is actually one of the works of faith, another fruit, and gift of the Spirit. It draws power out of God by creating a necessity according to the need. The power of God will hang around for a limited time. It does not mean that the gift goes with it. Gifts of God given to men are irrevocable. These gifts work through the power of God, which is stored in heaven (store your treasures in heaven where moth cannot eat, or thieves steal.) 
4. Thieves are the sons of darkness, the principalities of this world that will strip it off as soon as they get the chance, so use it for its purpose, according to your spiritual gift. Lingering with the power of God for too long will make it fly away before accomplishing its purpose. This is why the annointing of God is likened to a flowing river. There are other times that the power may stay on for days, even months, depending on the assignment it carries. Speaking of assignments, God empowers His ministering angels for an appointed work, or a counsel and the angels are more of extensions of the principalities, or powers that they carry.
5.  Engaging in the use of the power of God as a source of a feel-good kind of thing for men of God is dangerous as it puffs up the self. Self is the operating module of the devil, and once puffed-up, well, prepare for war. This is corruption of the water of the well flowing out of the children of God, an enemy working from the inside, so to say. The thorn in the flesh kind of situation arises like this. The wicked are usually drunk for all of the seasons. To them it is always time for party, revelings, indulgence(wickedness), and wicked spiritual power is at the center of this. 
6. The greatness and intensity of their power varies according to the extent of indulgence with the gods/powers of this world. There are actually folk whose power can be felt yards away. Some are mistaken for ministers of God, for their ability to perform miracles. The greater the indulgence with the works of darkness, especially so on a spiritual level, the greater the increase in their spiritual powers. For example, a temple of an idol would have a warm presence that would seem to be redidual at the venue so long as it is revered by its worshippers. These are the same powers at war with the Kingdom of God. I have heard preachers comment that they were always "drunk with the power of god." It is not advisable. For this reason, it is important to search the spirits of all men before getting yoked to them in the many ways that we do, like fellowships. Don't drink from this wells/powers of darkness. They are corrupt waters.
