“When a demon is cast out of a person, it roams around a dry region, looking for a place to rest, but never finds it. Then it says, ‘I’ll return to the house I moved out of,’ and so it goes back, only to find that the house is vacant, warm, and ready for it to move back in. So it goes looking for seven other demons more evil than itself, and they all enter together to live there. Then the person’s condition becomes much worse than it was in the beginning. This describes what will also happen to the people of this evil generation.”
Matthew 12:43‭-‬45 TPT

Cleaning our lives up (e.g. getting rid of bad habits) is never enough. We must invite Jesus to fill that empty space. David said, “I have taken your words to heart so I would not sin against you.” Psalms 119:11 NCV
The King James Version talks about hiding His word in my heart. In other words, we read, study, learn, and listen until it becomes part of us, and we are cooperating with the Holy Spirit to be conformed to the image of Jesus. If we want abundant life, nothing else will do.

It is important that we attend church regularly anywhere the word of God is proclaimed.
