Paul's Letter to Titus gives advice on how to life so that as we grow in age, we might also grow in wisdom and holiness.
Based on Titus 2:1-8,11-14
But as for you, teach what is consistent with sound doctrine. Tell the older men to be temperate, serious, prudent, and sound in faith, in love, and in endurance.
Likewise, tell the older women to be reverent in behaviour, not to be slanderers or slaves to drink; they are to teach what is good, so that they may encourage the young women to love their husbands, to love their children, to be self-controlled, chaste, good managers of the household, kind, being submissive to their husbands, so that the word of God may not be discredited.
Likewise, urge the younger men to be self-controlled. Show yourself in all respects a model of good works, and in your teaching show integrity, gravity, and sound speech that cannot be censured; then any opponent will be put to shame, having nothing evil to say of us.
For the grace of God has appeared, bringing salvation to all, training us to renounce impiety and worldly passions, and in the present age to live lives that are self-controlled, upright, and godly, while we wait for the blessed hope and the manifestation of the glory of our great God and Saviour, Jesus Christ. He it is who gave himself for us that he might redeem us from all iniquity and purify for himself a people of his own who are zealous for good deeds.
