Webster's defines proof as "Being able to Withstand or resists." And that is exactly what you can do to Satan's flames. Revelation 20: 9 states "They'll stream across the earth, surround and lay siege to the camp of God's holy people, the Beloved City. They'll no sooner get

there than fire will pour out of Heaven and burn them up. " Which means when Satan's army attacks God's people in the end times God will reign down fire but the fire will not harm God's chosen people. Because they have Jesus, who is basically the Ultamite fire
 

shield. This was shown when Shadrack, Meshack, and Abednego. When Nebuchadnezzar had them put inside the "furnace" they didn't burn up as quoted from Daniel 3: 20-26 20 "He ordered some strong men from the army to tie them up, hands and feet, and throw them
into the roaring furnace. 21Shadrach, Meshach, and Abednego, bound hand and foot, fully dressed from head to toe, were pitched into the roaring fire. 22Because the king was in such a hurry and the furnace was so hot, flames from the furnace killed the men who carried
 

Shadrach, Meshach, and Abednego to it, 23while the fire raged around Shadrach, Meshach, and Abednego.
24Suddenly King Nebuchadnezzar jumped up in alarm and said, "Didn't we throw three men, bound hand and foot, into the fire?"
 

"That's right, O king," they said.
25"But look!" he said. "I see four men, walking around freely in the fire, completely unharmed! And the fourth man looks like a son of

the gods!"
26Nebuchadnezzar went to the door of the roaring furnace and called in, "Shadrach, Meshach, and Abednego, servants of the High God,

come out here!"
Shadrach, Meshach, and Abednego walked out of the fire." And this was with the furnace 7 times hotter than usual. But God kept them
 

safe in  the flames, and he can also do the same for you.
