The most essential attribute a boy needs to become a man is the ability to receive instruction and correction. Proverbs makes it clear that nothing is more crucial (see 1:7, 4:13, 5:23, 10:17, 29:1, etc).
This is why a society that coddles boy can’t produce men. It only can produce manchilds who are easily offended and buck against the slightest critique.
Boys are like iron on anvil. The hammer of correction makes them tough and useful.
The same can be applied to a church. A church that refuses to correct will only produce frail and feeble Christians. Give praise to God if you have brethren and pastors that are willing to make you strong.
The fear of the Lord is the beginning of knowledge,
But fools despise wisdom and instruction (1:7).
Take firm hold of instruction, do not let go;
Keep her, for she is your life (4:13).
He shall die for lack of instruction,
And in the greatness of his folly he shall go astray (5:23).
He who keeps instruction is in the way of life,
But he who refuses correction goes astray (10:17).
He who is often rebuked, and hardens his neck,
Will suddenly be destroyed, and that without remedy (29:1).
