There are Christians who can’t understand why the Name of Jesus doesn’t seem to produce desired results for them. So, often, in frustration, they complain and say, “I tried using the name of Jesus to change things, but it didn’t work, why?”
It brings to mind the experience Jesus had with His disciples in Matthew 17:14-21. The disciples, had been trying to cast the devil out of a young guy, and it didn’t work, until Jesus showed up and asked what the matter was. At that point, the father of the boy who had the devil spoke up and said “Master, I brought my son to your disciples to cast the devil out and they couldn’t. If you can do anything, have compassion on us and help us.” Then Jesus cast the devil out of the little boy.
Afterwards, the disciples came to Him privately and asked “Master, why couldn’t we cast the devil out?” Then, Jesus answered and said, “Because of your unbelief.” Jesus identified their problem as unbelief. The same unbelief accounts for why the name of Jesus seems not to work for certain believers today. They use the name in unbelief.
For the Name of Jesus to be effective in your mouth, you’ve got to know the power behind that Name. And when you speak in the Name of Jesus, you should expect things to change. Don’t go observing circumstances and wondering whether they’ll change or not; only consider the Word, and the awesome power and authority behind that Name. That’s how to keep your faith steady and strong to apprehend your heart desire, using the Name of Jesus.
