If you instruct the brothers of these things, you will be a good servant of Christ Jesus, nourished in the words of the faith, and of the good doctrine which you have followed.
These things Paul instructs Timothy to command and teach (verse 11). In order to do so successfully, he must live such a noble life that none will reject him or his teaching because of his youthfulness. Instead he is to become a model believer in his personal conversation, his conduct, his love for God and man, his faithfulness to God’s will, and his spotless moral purity (verse 12).
