The notable day of the Lord is a constant motif throughout scripture. It refers to the Lord's second coming and his strange act of destroying the wicked, remaking the earth, and retrieving the saints into his kingdom. It's strange because it is contrary to the loving creator who has tolerated sin for so many years until he executes a final judgment on the wicked. Albeit, the notable day is joyous for those who have waited all of our lives or died with the vision of living in his kingdom.
