1 Finally then, brothers and sisters, we ask you and urge you in the Lord Jesus, that as you received instruction from us about how you must live and please God (as you are in fact living) that you do so more and more.2 For you know what commands we gave you through the Lord Jesus.3 For this is Godâ€(tm)s will: that you become holy, that you keep away from sexual immorality,4 that each of you know how to possess his own body in holiness and honor,5 not in lustful passion like the Gentiles who do not know God.6 In this matter no one should violate the rights of his brother or take advantage of him, because the Lord is the avenger in all these cases, as we also told you earlier and warned you solemnly.7 For God did not call us to impurity but in holiness.8 Consequently the one who rejects this is not rejecting human authority but God, who gives his Holy Spirit to you.
- Paul shifts from thanksgiving and relational updates to practical ethical instruction.
- The core exhortation is to live in a way that pleases God, building upon the foundation already laid (1 Thess 4:1).
- These instructions carry the authority of the Lord Jesus himself (1 Thess 4:2).
- God's explicit will for believers is their "sanctification" (hagiasmos), meaning being set apart for God and living a holy life (1 Thess 4:3).
- A primary aspect of sanctification involves abstaining from "sexual immorality" (porneia), a broad term covering various illicit sexual activities prevalent in the Greco-Roman world (1 Thess 4:3).
- Controlling one's own "body" (skeuos, possibly meaning 'vessel' or even 'wife' in context) in holiness and honor contrasts sharply with the uncontrolled "passionate lust" characteristic of those who don't know God (1 Thess 4:4-5).
- Sexual sin is not merely personal; it violates and exploits others within the community ("brother"), highlighting its social and relational consequences (1 Thess 4:6).
- God acts as the "avenger" against such exploitation, emphasizing the seriousness with which He views sexual sin and injustice (1 Thess 4:6).
- God's calling is fundamentally oriented towards holiness (hagiasmos), not impurity (akatharsia) (1 Thess 4:7).
- Rejecting these moral instructions is equivalent to rejecting God himself, who empowers holy living through the gift of the Holy Spirit (1 Thess 4:8).
