But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
2 Peter 3:8-10
9The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
10But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
The day will come. The moon will go dark.
Are you ready?
