Contrary to what some will tell you, God is not in charge here. He never wanted to be; He wanted us to be in charge. That’s why He gave Adam, the first man, dominion over creation. But that first guy - there's always one guy messing it up for the rest of us - gave that in-charge position away. Of course, God could have stepped in at that time and taken charge, but then He'd be in charge, which isn't what He wanted. So in order to restore things back to what God intended, a man had to step up and re-take charge.
But who among us could? Only God could. That’s why God had to come as a man to take charge, so that man would be in charge like He originally intended.
Just to paint the whole picture let's go back to the very beginning. The thing about God's sovereign will is that He generally chooses not to enforce it Himself. God created creation, and He was in charge of it. God then created man, and yielded His sovereignty to put man in charge of it. His deal with Adam was, I'll walk with you, talk with you, lend you an ear and give you advice, but what you say Adam, that’s what goes. You, Adam, are the authority.
So Adam then gives that authority away to satan. God could have, in His sovereign power, taken authority back from satan, but then that would put Him back in charge, and that was never His intent, His will. His intent/will was for man to have authority.
But again, who among us could do such a thing? Well, only God, coming to us as a man. So Christ comes and indeed takes back authority - in the spiritual realm. But, He has yet to return to this world to enforce it.
That's where our partnership comes in. It is our charge that we participate with Him in the enforcement of His authority, over the yet-to-be restored, and therefore still under the rule of satan creation. And we do that thru prayer and partnering in the gifts and manifestations of the Holy Spirit.
Maybe a simpler way to look at it is to compare it to a Sheriff and his deputies. The Sheriff is the one who holds authority, but he doesn't actually go out and patrol the streets. His deputies are the ones who go out and enforce the Sheriff's authority. Christ is the Sheriff, it's His authority. But until He returns to lay claim to the land, we are His deputies enforcing His will in a land run by criminals.
And while satan still rules this world, you can bet he's going to give us resistance. I've always said that you can tell how powerful one might be in the kingdom of God, by how hard hell works to hold them under. satan only attacks those he feels are a threat. Take that under consideration the next time you feel under attack. Which I assume by the sound of it is all the time.
We have Christ's authority to supersede that in the places and things we come in contact with. satan, the still-ruler of this world, is going to do everything he can to make us as stifled and stymied and irrelevant as he can. Jesus said in His Name we will do what He did, and even more. WE will do. Not ask Him to do, but WE will do. Your defense is in YOUR hands, with the most powerful weapon the universe has ever seen.
Strap on your armor and start swinging back. We DO eventually win this war. In the meantime, we are every bit the occupying army that is the US Soldier in Afghanistan. Don't be overwhelmed by attack, expect it. And be ready with your sword. God says persevere - this is a war of attrition, with the knowledge that we DO win in the end. But you still have to pick up your arms and swing back.
For now.
