The thesis of this presentation is that the Apostle Paul draws upon both Isaiah 59 and Wisdom (of Solomon) 5 as he exhorts the Thessalonian believers to be prepared for the Lord’s return by putting on noted pieces of armor. This proposition will be demonstrated by comparing the wording of each of these sources to that of 1 Thess. 5:8 as well as examining the broader contexts of all three passages looking for additional similarities in expression or thought. The discussion will proceed in the following manner: (1) A brief discussion of the Divine Warrior motif will be offered, establishing its relationship to the Day of the Lord when God comes in both judgment and deliverance; (2) Isa. 59:17 will be appraised. This will include examining the Divine Warrior language in vv. 15-20 as it most directly relates to this survey. The broader context will also be reviewed for the purpose of understanding the setting of the passage; (3) Wisdom 5:18 will next be evaluated. As with the passage from Isa., this assessment will focus on the immediate cotext of vv. 17-20 with its reference to the Divine Warrior as well as the backdrop of this passage within the larger context; (4) 1 Thess. 5:8 will be examined. Here the focus will be on any similarities in wording or thought with the Isa. and Wisdom passages. (5) The overall findings will be reviewed, and a final assessment will be given. Practical application will also be made of the conclusions to the church today.
