Let no one regard you with contempt because of your youth, but serve as an example to the believers in your speech and conduct, in your love, your faith, and your purity.
Let what you heard from the beginning remain in you. If what you heard from the beginning remains in you, then you will remain in the Son and in the Father.
Brethren, I exhort you in the name of our Lord Jesus Christ to be in full agreement with one another and not permit any divisions to arise among you. Be perfectly united in mind and purpose.
