That is about preaching . . . what about example??
"nor as being lords over those entrusted to you, but being examples to the flock." (1 Peter 5:3)
A lot of training can help you to feel you are somehow superior to those you preach to, like you are more because of your position and education. But what about maturity in Jesus? Our character can have a lot to do with how we can preach and how much we will actually minister grace.
If people don't know us personally, how can they feed on our example? Well, it can be done by faith and not by sight . . . by means of our prayer ministering grace. But our maturity can have a lot to do with if and how well we can minister for others to become mature in Jesus >
"Him we preach, warning every man and teaching every man in all wisdom, that we may present every man perfect in Christ Jesus. To this end I also labor, striving according to His working which works in me mightily." (Colossians 1:28-29)
Training alone can not do this, in my opinion. There is maturing in laboring according to how God is working within us.
"for it is God who works in you both to will and to do for His good pleasure." (Philippians 2:13)
And I note how our Apostle Paul tells us who qualifies to "take care of the church of God" >
"This is a faithful saying: If a man desires the position of a bishop, he desires a good work. A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach; not given to wine, not violent, not greedy for money, but gentle, not quarrelsome, not covetous; one who rules his own house well, having his children in submission with all reverence (for if a man does not know how to rule his own house, how will he take care of the church of God?); not a novice, lest being puffed up with pride he fall into the same condemnation as the devil. Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil." (1 Timothy 3:1-7)
There is not much here about being a good preacher, or knowing the Bible. But I see here how a man becomes what God's word means by a person who knows how to take care of people. This is a man who has learned at home, as his seminary, how to take care of people in a family way, like he has learned at home . . . with his wife helping him, so he knows how to labor with a godly woman . . . . not as an isolated individual.
And it looks like Paul and Sylvanus and Timothy learned from nursing mothers how to care for the children of God >
"But we were gentle among you, just as a nursing mother cherishes her own children." (1 Thessalonians 2:7)
So, the Thessalonians knew these great men personally, I would say, so they could feed on their example. To me, it seems these men had nursing mothers as part of their seminary training for laboring in our Heavenly Father's family caring and sharing way.
After all, God is called "our Father". And Jesus is His "Son". And the Holy Spirit labors to care for the children of God, and to prepare us for our Groom Jesus soon-coming. So, the Holy Spirit, though called "He", does have a mother's functions of caring for us children while preparing us for our Groom. Usually, in the cultures I have known, men do not have the function of bridal preparation
So, I can see, then, how God's ministering is a family example labor, with the man's lady helping him to find out how to relate Biblically in a close relationship so they can minister to other couples, and he learns with his children how to rule. And then his family can minister this example. And by the time he has developed and matured in such preparation and qualification, he has become "blameless" the way God's family and all-loving love cures our character.
We have people like this, but they can be sitting in the back of the church. And they can be ministering to and mentoring the ones at the front.
Meanwhile some number of ordained ministers actually are financial and building managers but who can preach. But that extra stuff can wear a person down, and we need to be "examples" of how Jesus gives us "rest for your souls" >
"'Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.'" (Matthew 11:29)
So, learning this is essential . . . not likely to come only with training and knowledge, but with how God cures our character to be submissive in His peace. Then is when we can obey Colossians 3:15 >
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
If people are getting ministered this, they can be mature enough to listen to and benefit from any child of God preaching, at any age. Because every child of God is able to minister God's own grace >
"Be hospitable to one another without grumbling. As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God." (1 Peter 4:9-10)
Children might preach about what they are learning at home, including about how to relate in a close relationship and how Jesus has us loving any and all people as ourselves, and other nations as our own, in His all-loving love; hearing if children are preaching this could be an interesting way to have accountability!
