Acts 2:19-21

And I will do powerful things in the sky that will shock everyone. The sun will turn dark, and the moon will turn red like blood. And I will do powerful things on the earth too. People will fight each other, and there will be fire and big smoke.” Then God’s really great and special day will come, and he will judge everybody. But God will save everybody that calls to him for help and asks him to save them.’ Joel wrote that in God’s book.”
