2 Thessalonians 2:13-17

But we should and are [morally] obligated [as debtors] always to give thanks to God for you, believers beloved by the Lord, because God has chosen you from the beginning for salvation through the sanctifying work of the Spirit [that sets you apart for God’s purpose] and by your faith in the truth [of God’s word that leads you to spiritual maturity]. It was to this end that He called you through our gospel [the good news of Jesus’ death, burial, and resurrection], so that you may obtain and share in the glory of our Lord Jesus Christ. So then, brothers and sisters, stand firm and hold [tightly] to the traditions which you were taught, whether by word of mouth or by letter from us. Now may our Lord Jesus Christ Himself and God our Father, who has loved us and given us everlasting comfort and encouragement and the good [well-founded] hope [of salvation] by His grace, comfort and encourage and strengthen your hearts [keeping them steadfast and on course] in every good work and word.
