Passage
who shall pay the penalty [of] everlasting destruction from [the] presence of the Lord, and from the glory of his might,
who shall pay the penalty [of] everlasting destruction from [the] presence of the Lord, and from the glory of his might,
2 Thessalonians 1:7 and to you that are troubled repose with us, at the revelation of the Lord Jesus from heaven, with [the] angels of his power,
2 Thessalonians 1:8 in flaming fire taking vengeance on those who know not God, and those who do not obey the glad tidings of our Lord Jesus Christ;
2 Thessalonians 1:9 who shall pay the penalty [of] everlasting destruction from [the] presence of the Lord, and from the glory of his might,
2 Thessalonians 1:10 when he shall have come to be glorified in his saints, and wondered at in all that have believed, (for our testimony to you has been believed,) in that day.
2 Thessalonians 1:11 To which end we also pray always for you, that our God may count you worthy of the calling, and fulfil all [the] good pleasure of [his] goodness and [the] work of faith with power,
The verse centers on "shall", "penalty", "everlasting", "destruction", "presence", "lord", "glory", and "might". It is saying that the verse draws attention to "shall" and "penalty", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "in flaming fire taking vengeance on those..." into verse 10's "when he shall have come to be...", so "shall" and "penalty" belong inside that flow. In 2 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "shall" and "penalty" with trust shaped by these words, not by a vague optimism outside the passage.
