In 2 Thessalonians, Paul again includes an exhortation to live sanctified lives:
2 Thess 2:13-15
13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
Paul instructs the church that part of our holiness to God includes separating from some worldly things and even from some people:
2 Thess 3:5-6
5 And the Lord direct your hearts into the love of God, and into the patient waiting for Christ.
6 Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us.
But even when separating from someone, we are to consider them as brothers, not enemies:
2 Thess 3:14-15
14 And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.
15 Yet count him not as an enemy, but admonish him as a brother.
He ends with the common salutation with his own hand:
2 Thessalonians 3:17 The salutation of Paul with mine own hand, which is the token in every epistle: so I write.
We recall from 2 Thessalonians 2:2 that Paul warned the church to be wary of any “letter as from us,” giving another message. Paul had obviously been concerned about pseudo letters that were circulating in his name so he signed his letters personally.
1 Corinthians 16:21 The salutation of me Paul with mine own hand.
Colossians 4:18 The salutation by the hand of me Paul. Remember my bonds. Grace be with you. Amen.
And when Paul wrote, he also wrote with rather large print as expressed in:
Galatians 6:11 Ye see how large a letter I have written unto you with mine own hand.
