And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
All Commentaries on 1 Thessalonians 5:23 Go To 1 Thessalonians 5
Ambrose of Milan
AD 397
On this subject the Lord says, “When you come into the land to which I bring you and when you eat of the food of the land, you shall present an offering to the Lord. When you separate the firstfruits of your barn floors, you shall also give the firstfruits of your dough to the Lord.” We are a composite of diverse elements mixed together, cold with hot, and moist with dry. This mixture is the source of many pleasures and manifold delights of the flesh. But these are not the firstfruits of this body of ours. Since we are composed of soul and body and spirit, the first place is held by that mixture in which the apostle desires that we find sanctification. “And may the God of peace himself sanctify you completely, and may your spirit and soul and body be preserved sound, blameless at the coming of our Lord Jesus Christ.” .
