2 Thessalonians 2:13-15

Amplified Bible, Classic Edition

¹³ But we, brethren beloved by the Lord, ought and are obligated [as those who are in debt] to give thanks always to God for you, because God chose you from the beginning ^[a]as His firstfruits (first converts) for salvation through the sanctifying work of the [Holy] Spirit and [your] belief in (adherence to, trust in, and reliance on) the Truth.

¹⁴ [It was] to this end that He called you through our Gospel, so that you may obtain and share in the glory of our Lord Jesus Christ (the Messiah).

¹⁵ So then, brethren, stand firm and hold fast to the traditions and instructions which you were taught by us, whether by our word of mouth or by letter.
