The sinners in Zion are terrified; trembling grips the godless: “Who of us can dwell with the consuming fire? Who of us can dwell with everlasting burning?” Those who walk righteously and speak what is right, who reject gain from extortion and keep their hands from accepting bribes, who stop their ears against plots of murder and shut their eyes against contemplating evil– they are the ones who will dwell on the heights, whose refuge will be the mountain fortress. Their bread will be supplied, and water will not fail them. Your eyes will see the king in his beauty and view a land that stretches afar. Isaiah 33:14-17 NIV
When Jesus returns, as stated in 1 Thessalonians 4:16, there will be two groups of people. Those that are waiting and those that are not. Those who are honest and love the LORD will be so excited to see Him. However, those that are not ready will be fearful. I want to be in the group that is ready.
The heavens receded like a scroll being rolled up, and every mountain and island was removed from its place. Then the kings of the earth, the princes, the generals, the rich, the mighty, and everyone else, both slave and free, hid in caves and among the rocks of the mountains. They called to the mountains and the rocks, “Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb! For the great day of their wrath has come, and who can withstand it?” Revelation 6:14-17 NIV
