Wow! I think this might be the first time in 296 posts that we come to the end of both an Old and New Testament book on the same day! So yes, we end both Job and 1 Thessalonians today :)
After Paul reassures the young Thessalonian church of their salvation and exhorts them to continue working (as opposed to being idle) until the day of the Lord comes, like a thief in the night…Paul ends his book with a plethora of miscellaneous commands.
Similarly, after Solomon makes his case that wisdom is better than folly, he spends the last few chapters of Ecclesiastes giving a plethora of wisdom sayings.
With so much miscellaneous information, it’s hard to find a common thread! But each man makes a focused summary at the end of his book.
Solomon ends Ecclesiastes with the decisive statement:
Fear God and keep his commandments, for this is the whole duty of man. For God will bring every deed into judgment, with every secret thing, whether good or evil (Ecclesiastes 12:14).
And Paul ends his letter to the Thessalonian church with profound encouragement:
Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ. He who calls you is faithful; he will surely do it (1 Thessalonians 5:23-24).
I can’t think of better ending sentiments… A command to fear God, a prayer for God’s sanctification, and the assurance of God’s faithfulness to complete the work he’s started in us. That sounds like the gospel. That sounds like good news!
