Day of the Lord

A period of time when the Lord Jesus will visibly appear on earth in power and glory to exercise judgment and subsequently establish His kingdom of peace (2 Thes 1:6-8; 2:2, 3, 8). This day is already announced in the OT, where the focus is primarily on the judgments (Isa 2:12; Zeph 1:14-18; Mal 3:19).
