[5:9] 1 sn God did not destine us for wrath. In context this refers to the outpouring of God’s wrath on the earth in the day of the Lord (1 Thess 5:2-4).
[5:10] 2 tn Grk “the one who died,” describing Jesus Christ (1 Thess 5:9). Because of the length and complexity of the Greek sentence, a new sentence was started at the beginning of v. 10 in the translation.
[5:10] 3 sn The phrases alert or asleep may be understood (1) of moral alertness (living in faith, love, and hope as vv. 6, 8 call for, versus being unresponsive to God) or (2) of physical life and death (whether alive or dead). The first fits better with the context of 5:1-9, while the second returns to the point Paul started with in 4:13-18 (no disadvantage for the believing dead).
