2 Thessalonians 2:13-17 - Stand Firm And Hold Fast
13 But we ought to give thanks to God always for you, brethren, beloved by the Lord; because God, from the beginning, chose you to salvation, in sanctification of the Spirit and belief of truth; 14 unto which He called you through our Gospel, to an obtaining of the glory of our Lord Jesus Christ. 15 So, then, brethren, stand fast, and hold the instructions which ye were taught, whether through speech, or through letter of ours.
16 Now our Lord Jesus Christ Himself, and God our Father Who loved us and gave us eternal consolation and good hope in grace. 17 comfort your hearts, and establish, you in every good work and word.
