What does the fire represent in the life of believers?

Fire can represent several spiritual truths for believers, particularly in terms of purification and empowerment. In the context of the sermon, the fire of coals reflects both the cleansing processes God uses in our lives and the empowering presence of the Holy Spirit, which enables us to fulfill God's will. The fire invites us to consider how trials can refine our faith and produce growth, much like Peter's experience where his reliance on self was shattered. The fire serves as a means of sanctification, illustrating God's continual work in believers to draw them closer to Him.
