The Gospel changes people. Most profoundly, it changes men. Men who either slink around with no responsibility and sensibility, or who parade around with a wild and free dominance, are all changed by the Gospel. The murderous Saul was changed by the Gospel into the patient and truth-bound Paul. The idol-worshipping Abram became the faith-justified Abraham. The abuser of other people on the other cross became the defender of His Saviour, the Lord Jesus. The quiet and secretive Nicodemus stood with Joseph of Arimathea to honour the body of the Christ.
The Gospel changes men – be they old, or young. It might be true that one cannot teach an old dog new tricks, but men are not dogs, and the Gospel can teach anyone new tricks.
Older men are to be sober-minded, dignified, self-controlled, sound in faith, in love, and in steadfastness. Likewise, urge the younger men to be sensible.Titus 2:2, 6
These verses make it clear that the Gospel will evidence itself through the change it produces in older and younger men.
The Gospel will take aimless men, and call them to be clear and sober minded.
The Gospel will transform the shameless deeds and sayings of men, and turn them into dignified and respectable men.
The Gospel will get the lazy and easily misguided men, and make them walk with self-control and conviction.
The Gospel will energise men who barely know the Bible, give them a hunger and thirst for righteousness, and make them sound in faith.
The Gospel will take the easy quitters and inconsistent among men, and prove them to be steadfast, reliable, and faithful.
The Gospel will take the naivety and impulsiveness of young men, and make them sensible.
As one man once said:
and we can add
Younger men, be sensible.
