The devil is afraid of a worshipping people. He actually doesn’t mind complacent worship, as it seems to work opposite to the real thing – it deadens our sensitivities to the Holy Spirit of God. It works completely opposite to the effects of sold out, passionate worship. Complacent worship is an oxymoron.

“Sold out, passionate worship”, reminds me of the Lord’s stirring talk with the woman at the well :
“From now on, worshiping the Father will not be a matter of the right place but with a right heart. For God is a Spirit, and He longs to have sincere worshipers who adore him in the realm of the Spirit and in truth.””
John 4:23-24 TPT
“He longs”, we long. Burning hearts.
