The fire of God in our hearts is been translated into passion, holy zeal for the Word of God. The Word of God inside of you can make you too hot for the adversaires to handle. Carry fire, stand your ground and maintain your victory already given to you by Jesus Christ, Jeremaih 20:9, "The Word of God is in my heart is like a fire, a fire shut up in my bones." The fire of God inside of you will give you boldness to proclaim the Gospel to the nations.
