¹⁵ So then, brothers and sisters, stand firm and hold fast to the teachings^[c] we passed on to you, whether by word of mouth or by letter. 2 Thessalonians 2:15

This verse comes from a very encouraging passage where Paul is talking to the Thessalonians.

¹³ But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits^[b] to be saved through the sanctifying work of the Spirit and through belief in the truth. ¹⁴ He called you to this through our gospel, that you might share in the glory of our Lord Jesus Christ. ¹⁵ So then, brothers and sisters, stand firm and hold fast to the teachings^[c] we passed on to you, whether by word of mouth or by letter. ¹⁶ May our Lord Jesus Christ himself and God our Father, who loved us and by his grace gave us eternal encouragement and good hope,¹⁷ encourage your hearts and strengthen you in every good deed and word.

Honestly I could go through this passage line-by-line and dissect each point, but nothing speaks more clearly than the word of God. This passage is so rich, and it is a reminder for us about who we are and who we are called to be.

I encourage you to read the above a few times, let it sink in and know that this is my prayer for you today (and everyday!)

I have hidden your word in my heart
    that I might not sin against you. Psalm 119:11
