In everything set them an example by doing what is good. In your teaching show integrity, seriousness and soundness of speech that cannot be condemned, so that those who oppose you may be ashamed because they have nothing bad to say about us. Titus 2:7-8
In reading the commentary about this scripture, I have found that there is a two fold purpose as to why Paul includes this in his message about helping the family within the churches in Crete. More specifically, addressing the demographics with in the Cretan churches: older women, younger women, older men, younger men, and slaves. Paul chooses not only encourage and give directions to Titus, but also disciple his heart in the man of God he needs to be to lead those churches.
Paul has finished laying the ground work as to what Titus needs to accomplish the missionary there, and then once the structure within the church has been defined, he moves on to demonstrating how God needs those Titus surrounds himself with to serve the church. I imagine that once Titus got his core group of elders and respectable men within the church, he went about training them. I can't help but think about the growth Titus had to go through in teaching older men how to be Godly. Jim said it best, "you need to keep putting together lessons and practice preaching to stay in good practice, even if it is to a room of your kid's stuffed animals.
I need to get on that, after all, isn't that what Paul had meant when he gave encouragement to Philemon [6] to "...be active in sharing [his] faith...?" I know for me, I used to do this, and I need to return to it.
