Charles Ellicott Commentary 1 Thessalonians 5:24

"Faithful is he that calleth you, who will also do it." — 1 Thessalonians 5:24 (ASV)

Faithful is he.—A reason for hoping confidently that they will be blamelessly preserved. God would forfeit His character for keeping His promise, if He “called,” and did not enable men to obey the call. Of course He can only “do it” in case they continue willing to have it done. On the present tense, see Note on 1 Thessalonians 2:12.
