How do we know that fire symbolizes God's glory?

Fire represents God's glory in various biblical narratives. From the burning bush experienced by Moses to the tongues of fire that descended on the disciples at Pentecost, fire signifies God's holy presence and His ability to purify and empower. In the sermon, it is noted that the fire that fell upon the disciples not only demonstrated God's power but also showcased His purpose to call His people to Him. This symbolism reinforces the idea that where God's fire resides, His authority and transformative presence are evident, as He works out His will among His creation.
