It's not any of those minor things. He will be wiping out most of the life on the planet.
I will show wonders in the heavens and on the earth, blood and fire and billows of smoke. The sun will be turned to darkness and the moon to blood before the coming of the great and terrible day of the LORD. And everyone who calls on the name of the LORD will be saved; -- Joel 2:31-32 as quoted by Peter in Acts 2:20
The Bible is full of such warnings. I take them seriously. The phrase “the day of the Lord” is used nineteen times in the Old Testament (Isaiah 2:12; 13:6, 9; Ezekiel 13:5, 30:3; Joel 1:15, 2:1,11,31; 3:14; Amos 5:18,20; Obadiah 15; Zephaniah 1:7,14; Zechariah 14:1; Malachi. 4:5) and five times in the New Testament (Acts 2:20; 1 Thessalonians 5:2; 2 Thessalonians 2:2; 2 Peter 3:10). It is also alluded to in other passages (Revelation 6:17; 16:14).
“I will utterly sweep away everything
from the face of the earth,” declares the Lord.
“I will sweep away man and beast;
I will sweep away the birds of the heavens
and the fish of the sea,
and the rubble with the wicked.
I will cut off mankind
from the face of the earth,” declares the Lord. -- Zephaniah 1:2-3
Meanwhile, you sound like you are choosing to be in the same position with the same hateful, impotent attitude as Kahn, quoting from Moby Dick:
Only they are smart enough to tremble.
Or will you declare that since you don't like what God Almighty has done and what He states over and over again that He will surely do, you will teach Him a lesson and deny His existence?
