Proverbs 3:24-26
24 When thou liest down, thou shalt not be afraid: yea, thou shalt lie down, and thy sleep shall be sweet.
25 Be not afraid of sudden fear, neither of the desolation of the wicked, when it cometh.
26 For the Lord shall be thy confidence, and shall keep thy foot from being taken.
Why do Christians worry about the destruction the wicked world is going to face? They act as if they will be destroyed as well. However, throughout the entire Bible, God destroys the wicked but always saves his people from it. You may see the destruction, but God is our protection. So, stop worrying about the destruction that is to come, instead worry about the ones that you can lead to Christ.
