Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord because you know that in the Lord your labor is not in vain.
Only, live your life in a manner worthy of the gospel of Christ, so that, whether I come and see you or am absent and hear about you, I will know that you are standing firm in one spirit, striving side by side with one mind for the faith of the gospel
provided that you continue securely established and steadfast in the faith, without shifting from the hope promised by the gospel that you heard, which has been proclaimed to every creature under heaven. I, Paul, became a minister of this gospel.
And after you have suffered for a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, support, strengthen, and establish you.
Remember, then, what you received and heard; obey it and repent. If you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.
