But the Lord is faithful, who shall establish you, and keep you from evil.
All Commentaries on 2 Thessalonians 3:3 Go To 2 Thessalonians 3
Nicholas of Lyra
AD 1349
But God is faithful: That is, He always fulfills His promises.
He will strengthen you: That is, against the deceptions of the false apostles.
and he will guard you from evil: Especially while under persecution and tyrrany.
