Paul writes to Titus in chapter 2 about encouragement and teaching for the churches he would visit and the men and women he would teach. He speaks about older men, older women, young women, younger men, children, slaves and so on. A common instruction or characteristic he wanted them to grow in was sensibility.
Your Bible might read self-control, but what does it mean to be sensible? How can we be sensible or improve in sensibility? And what will this lead to in our lives?
