“But the Lord is faithful, and He will strengthen and protect you from the evil one.” ‭‭2 Thessalonians‬ ‭3‬:‭3‬ ‭NASB1995‬‬

God is a keeper of his promises

The Lord is FAITHFUL. God is faithful in regard to creation (Ps 119:90), His promises (Dt 7:9; 2Co 1:18; Heb 10:23), salvation (1Th 5:24), temptation (1Co 10:13), suffering (1Pe 4:19), and here faithful to strengthen and protect from Satan (cf. Jn 17:15; Eph 6:16; 1Th 3:5).
