The aged men must be sober (maintaining self-judgment), temperate, with love and patience. Aged women must conduct themselves in holiness, teachers of good things that relate to the home, teaching the younger women to be keepers at home and obedient to their husbands.
What a loss and a disgrace to the Christian testimony for wives whose husbands provide, to leave their children and their homes to seek employment outside. Children need their parents, especially their mother, every moment of their childhood and youth. We bring our children up either for Christ or Satan. Their decisions in maturity depend largely upon what their mother in love has taught them. Children without a father's care lose much in their early lives.
Young men should be taught to practice the truth that is after godliness. Servants (slaves) are exhorted to show the truths of godliness before their masters. Believing masters have a common interest with believing slaves.
Verses 11 through 15 summarize Christianity. The grace of God appeared bringing salvation to faith. The practice of Christian life is set forth. Our precious Savior is coming soon for His saints, our hope, and to appear before a wicked world. He gave Himself to redeem us from all iniquity and call us as a special treasure and purchase to Himself.
