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.
All Scripture is inspired by God and is useful for teaching, for refutation, for correction, and for training in uprightness, so that the man of God may be proficient and equipped for good work of every kind.
