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.
Do not worry about anything, but present your needs to God in prayer and petition, with thanksgiving. Then the peace of God, which is beyond all understanding, will guard your hearts and your minds in Christ Jesus.
