Fire

“For our God is a consuming fire.” (Heb. 4:29 ESV)

Your faith is tested by fire

“So that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ.” (1 Peter 1:7 ESV)

Jesus baptizes with the Holy Spirit and with Fire 

“John answered them all, saying, “I baptize you with water, but he who is mightier than I is coming, the strap of whose sandals I am not worthy to untie. He will baptize you with the Holy Spirit and with fire.” (Luke 3:16 ESV)

His word is like fire

“Is not my word like fire, declares the Lord, and like a hammer that breaks the rock in pieces?” (Jer. 23:29 ESV)

The foundation of your work will be tested through fire

“For no one can lay a foundation other than that which is laid, which is Jesus Christ. Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, straw— each one's work will become manifest, for the Day will disclose it, because it will be revealed by fire, and the fire will test what sort of work each one has done. If the work that anyone has built on the foundation survives, he will receive a reward. If anyone's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire.” (1 Cor. 3:11-15 ESV)
