"Fire" in the Bible is almost always to do with God's judgement. The idea of fire being the Holy Spirit is wrong. The Holy Spirit appeared to be like "tongues of fire". Yes, it does matter. I've heard people praying for God's fire to fall. They do not know what they are asking.
Luke 9:54
"When the disciples James and John saw this, they asked, “Lord, do You want us to call down fire from heaven to consume them?”
But Jesus turned and rebuked them.
Hebrews 12:29
“For our God is a consuming fire.”
