Paul doesn’t ASSUME believers will automatically live a life in line with the doctrine they have believed. This is a temptation preachers can give in to. There is, and always will be, a specific place – a vital need – for exhortation. Don’t just teach the sound doctrine – teach what ACCORDS with it. Lifestyle, choices, etc.
This is why Titus needs to be tough (good thing he was. He has a tough name too. Paul might have been more worried if he was writing to someone called Rupert). People like debating doctrine all day – but when you suggest their life changes it gets awkward.
But here’s the thing – it must accord with sound doctrine: the grace, which teaches us to say no to ungodliness. How does it do that? It replaces ungodly passions with godly zeal…
With this in place we can be exhorted/instructed as to how we should live… if this is not in place – the exhortation is either water off a duck’s back, a provocation, a miserable burden or a reason for smug moralistic pride…
So the work of Christ comes first. He purifies us and makes this life possible. So how does sound doctrine express itself thru men? N.B. All of Paul’s exhortations have a missional focus. The gospel must have a good rep in the city. Titus needs to ensure this. Guys being stupid are harming the progress of the gospel by distorting it.
The older guys are called to sobriety, dignity, self-control and soundness in faith, love and steadfastness… Paul is using his faith, hope and love trio – but the hope is being expressed in terms of steadfastness. For older guys this would appear the way it shows. Maybe hope is an easier thing for young guys – so older men are called to be sound in steadfastness.
Young men need to be self controlled – and Titus needs to exemplify this. So that men will never shame the gospel.
