The Kingdom of God is NOT a Revolutionary Power. Instead it is really THE power. As the apostle John said,

“You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world.”
Jn 4:4

If we are truly Christians, God has translated us out of Satan’s power into God’s kingdom.

“who delivered us out of the power of darkness, and translated us into the Kingdom of the Son of his love”
Col 1:13

God is in control

Yes, Satan is allowed some power here to reward his servants. He tells Jesus,

“5 The devil, leading him up on a high mountain, showed him all the kingdoms of the world in a moment of time. 6 The devil said to him, “I will give you all this authority, and their glory, for it has been delivered to me; and I give it to whomever I want. 7 If you therefore will worship before me, it will all be yours.” ”
Lk 4:5-7

Jesus does not deny this power, but says it only appropriate to worship the Lord our God!

Satan’s power and rule is only by permission. Indeed, of the governments of our world it says,

“1 Let every soul be in subjection to the higher authorities, for there is no authority except from God, and those who exist are ordained by God.”
Rom 13:1

God overrules all.

There has been a hand off to the Son

In Psalm 2 it speaks of giving “my son,” verse 7, rule over the nations, Psa 2:8-9. The judges and rulers of the earth (Psa 2:10) are allowed a measure of liberty, as is Satan and you and I, but they are warned,

“Kiss the son, lest he be angry, and you perish in the way,
For his wrath will soon be kindled.
Blessed are all those who take refuge in him.”
Psa 2:12

Peter was an outstanding apostle,

both before and after Christ’s death, but though very aggressive in nature, was at times perhaps had a little too much confidence in himself as a man.

“The Lord said, “Simon, Simon, behold, Satan asked to have you, that he might sift you as wheat,”
Lk 22:31

Satan can only do what he is allowed to do.

Satan’s power is all by permission!

Satan cannot even tempt the Christian beyond individually set limits,

“No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it. ”
1Cor 10:13

There will even be a period in history when Satan, “that he should deceive the nations no more,” Rev 20:3, and the world is able to see through the Satanic designs.

Finally “… he must be freed for a short time,” Rev 20:3

For a short period of testing, just before the end of our universe.
