Read 1 Thessalonians 3:13 Using Other Translations
To the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints.
so that he may establish your hearts blameless in holiness before our God and Father, at the coming of our Lord Jesus with all his saints.
May he, as a result, make your hearts strong, blameless, and holy as you stand before God our Father when our Lord Jesus comes again with all his holy people. Amen.
