1 Thessalonians 5:2 states that the Day of the LORD will come as a thief in the night. Reading about the Day of the Lord, most people think only in negative terms: the wrath of God against sinners. Chapter five reveals both a negative and a positive aspect to this event on God’s prophetic calendar. Indeed, sinners are appointed to wrath (5:1-3, 9) but saints (those who are in Christ) are appointed to salvation (5:4-11).
