Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.
1 Thessalonians 3:12-13
12 And may the Lord make you increase and abound in love to one another and to all, just as we do to you, 13 so that He may establish your hearts blameless in holiness before our God and Father at the coming of our Lord Jesus Christ with all His saints.
