This ignorance of our authority in & through Christ Jesus will be our undoing. This reminds me of an incident a few years back that gave me great insight. It had to do with condiments that remained from my cooking session–pepper and onions. I had left them in a plate in the open air to preserve them.
You might ask, how about your fridge? Well, I asked myself that question too. I'd not had a fridge for a while and so it was easy to forget that I now had a preservation system and took my normal route of preservation. Before then, I'd contemplated steaming them since they were not going to be put to use anytime soon.
Long story short, when this happened what dropped in my mind was that as believers, this is is what we do too. When we enter into God's kingdom, we've been completely saved and the old things have passed away, but we forget that. We forget that we've come into power and authority and carry on living like we used to, fearing what we once feared and generally carrying on like nothing's changed in our lives.
I dearly hope that from today, you begin to walk & operate in the authority that God has so graciously given us through His son, Jesus Christ.
