Closing Benediction and Exhortations (vv. 23–28)

Assurance of Sanctification and Preservation (vv. 23–24)

“The very God of peace sanctify you wholly… your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.”
Modern versions weaken this to a wish (“may the God of peace…”), misunderstanding the optative mood.
Optative in prayer = dependence, not uncertainty; outcome rests on God’s action.
The KJV properly captures the assurance—God will sanctify and preserve.
“Spirit and soul and body” affirms:
- Completeness of God’s work.
- Distinction (and possible division) between the immaterial parts (cf. Hebrews 4:12).
The preservation extends “unto the coming of our Lord Jesus Christ.”
- Context points to the Second Coming, not the rapture.
- At the rapture, body, soul, and spirit reunite.
- At the Second Coming, saints stand whole and sanctified before the Lord (cf. 1 Thessalonians 3:13).

“Faithful is he that calleth you, who also will do it.”
Removes all doubt: God will accomplish what He began.
Marked green—language tied to the kingdom calling, not Body of Christ doctrine.
“Calleth” (kaleō) = to invite or summon; not irresistible election.
Contextual reference: 1 Thessalonians 2:12—called “unto his kingdom and glory.”
- Refers to Israel’s prophetic kingdom hope.
For today’s Body of Christ, principle still applies: God is faithful in every dispensation.
- Cf. Philippians 1:6—He who began the work will complete it.
The unchanging truth: God’s faithfulness guarantees the fulfillment of His purpose.
