"How do I know when I'm operating in the Holy Spirit?"
The Holy Spirit's presence in your life will make all the difference between living in victory and living in defeat.
In response to your question, I want to give you three questions that you need to ask yourself. The first question is, "What is the thing that preoccupies my mind the most?" The second question is, "What ambitions drive me and energize me?" And the third question is, "How do I spend my time and my energy?" Beloved, the answer to these questions will help you to know if the Holy Spirit is in His rightful place in your life or not.
Some believers, after operating by the Holy Spirit, fall back into operating by their flesh. Why? You'll find there are two reasons: Either the Holy Spirit is being grieved as you continually live in sin, or He is being quenched as you ignore His teaching in His book, the Bible.
The Holy Spirit is a gentleman. He grieves easily, and He's quenched easily. Not only that, He must be welcomed in on a regular basis—not just once. But His presence in your life will make all the difference between living in victory and living in defeat.
