Living as a Christian means more than believing the right things—it means living differently than the world around us. The Apostle Paul instructed Titus to teach sound doctrine not just with words but through transformed lives. Paul gave specific instructions for different groups: older men should be temperate and worthy of respect, older women should be reverent and teach what is good, younger women should love their families and be self-controlled, and young men should focus on self-control. These high standards matter because if we live differently than the world, we'll make a difference in the world, shining like stars against the darkness of sin.
