You probably read the title there and immediately thought “well, duh! God!” That is what you should think, but it often isn’t how we act. We often act like we are constantly at odds with the devil, which we are, but the thing we don’t realize is that our savior already won.
We don’t want to give the devil more credit than he deserves. You shouldn’t be too worried when bad things are happening somewhere. Don’t say “oh, the devil is really active there, those poor people.” Instead ask God to make that place a safe haven, where the devil is blocked by a fifty foot wall. Blaming everything bad on the devil doesn’t help at all, letting God in does.
Here’s another way to look at it. Say I have a problem with being mean to other people. If all I ever do is blame it on the devil will I feel any responsibility to stop. No! I should be praying for God to help me stop, and then actively trying to stop. Even if the devil is causing my issues I should act like God is more powerful. We have been given authority over the Earth in God’s name, we should act like it.
1 Peter 3:22 — Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him.
