Ephesians 6:24

Grace be with all them... — The salutation, “Grace be with you,” in various forms, is, as St. Paul himself says in 2 Thessalonians 3:17, “the token,” or characteristic signature, in every one of his Epistles, written with his own hand. It may be noted that it is not found in the Epistles of St. James, St. Peter, St. Jude and St. John, and that it is found in the Epistle to the Hebrews. Here, however, it is at once general and conditional, “to all them who love the Lord Jesus Christ.” So in 1 Corinthians 16:22, “If any man love not the Lord Jesus Christ, let him be anathema.”

In sincerity. — The original is far stronger, “in incorruptibility,” a word usually applied to the immortality of heaven (as in Romans 2:7; 1 Corinthians 15:42; 1 Corinthians 15:50; 1 Corinthians 15:53; 2 Timothy 1:10); only here and in Titus 2:7, applied to human character on earth. Here it evidently means “with a love immortal and imperishable,” incapable either of corruption or of decay, a foretaste of the eternal communion in heaven.
