The enemy also knows he can lull us to sleep with everything our eyes see and everything we experience. He's great at singing lullabies. In fact, I'd say he's probably got the best voice ever. He was created to be the most beautiful angel. But then he rebelled because he wasn't content to be the most beautiful angel. He wanted to be God.
So, he lives to make us Christians ineffective. If we are ineffective, then God's work is at a standstill. God has chosen to work through us.
How do we wake up to the spiritual war?
First, remember you are in a battle. Sometimes this is easy if the fighting is intense. Often, this fact gets lost because we are just coasting a long just doing life.
Second, realize how you live out your faith is part of your fighting power. Are you content? Are you encouraged? Are you living by faith or by sight? Are you purposely choosing to beleive when your flesh just wants to get through the day?
Third, pray. Pray throughout the day. Let Jesus be a part of your ongoing conversation with the day. In prayer we take on the evil forces. In prayer God's power is loosed into situations.
Fourth, remember wherever you go the Spirit goes with you. He lives within you if you are a Believer. When you enter the room, God does too. Think on that for a while.
Fifth, remember the fight isn't with people. It is "against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places." Ephesians 6:12
The enemy loves it when we see people as the problem. He loves it when we gossip. He loves it when we attack others rather than him and his forces. Read the verse above again. Evil is super organized. Evil has a plan. So, we have to enter God's plan and let Him work it out through us.
Sixth, don't settle for a meaningless existence. Don't pursue things that are going to just burn up in the end. Live for stuff that counts.
That list will get you started fighting today. There are a whole lot more things I could have written. Read the Word -- that is a fighting text! We are in a fight. There's a lot more going on in the unseen realm than there is in this world that we do see. Remember that. And you are important in this fight!
