2 Thessalonians 2:1-3 Revised Standard Version (RSV)
The Man of Lawlessness
2 Now concerning the coming of our Lord Jesus Christ and our assembling to meet him, we beg you, brethren, 2 not to be quickly shaken in mind or excited, either by spirit or by word, or by letter purporting to be from us, to the effect that the day of the Lord has come. 3 Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness[a] is revealed, the son of perdition,
2 Thessalonians 2:13-17 Revised Standard Version (RSV)
Chosen for Salvation
13 But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God chose you from the beginning[a] to be saved, through sanctification by the Spirit[b] and belief in the truth. 14 To this he called you through our gospel, so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
16 Now may our Lord Jesus Christ himself, and God our Father, who loved us and gave us eternal comfort and good hope through grace, 17 comfort your hearts and establish them in every good work and word.
