Rom 12:11 Never be lazy in showing such devotion. Be on fire with the Spirit. Serve the Lord. (ISV).
One of our devotion is prayer. We might be in a holiday season which is nice and great but we do not go on holidays for spiritual things!
One of the ways of maintaining the fire is to spend at least some periods in devotion to God. Sometimes spending at least one hour praying in tongues greatly helps to maintain the fire.
Still spend time in God’s word. Maintain the fire.
Keep the devotion.
Don’t become lazy!
