To be on fire for the Lord is to be fervent in spirit (in the Spirit). It is to be aglow in the Holy Ghost and maintain the spiritual glow. How is your spiritual life hot, lukewarm, or cold? We need to be red-hot in our spiritual and Christian lives. When you are on fire for God, no demon or witch will harm you. Can files perch on hot boiling oil? Impossible Can you match on hot iron with your natural bare foot? No If you maintain a red-hot spiritual life, don't worry about the devil, for he is a defeated foe before you. He that is on fire for the Lord should fear no being, but God."
