Pastors must not be more punchy than necessary, but they must be as punchy as needed.
1 Timothy 3:2-3
A bishop then must be blameless... no striker... not a brawler.
A pastor must not be looking to stir up trouble or to create tensions where there aren't any. He can't be the kind of guy who looks for a fight. But he must not be the kind of guy who is always anxious that a fight may break out. He cannot be scared of trouble or uncomfortable with tension.
Psalm 23:1-2
The Lord is my shepherd; I shall not want.
He maketh me to lie down in green pastures:
he leadeth me beside the still waters.
Many of the fights churchmen have could be avoided by having a clearer, punchier word from their pastor. When pastors let things slide, they leave it for their people to clean up. If they do not lead with strength, they leave the people to their weaknesses, which always results in more conflict, more resentment, less forgiveness, and less harmony.
People do not naturally find themselves by still water. They need to be led there. If pastors will not do the hard work of disciplining his people, he leaves them to the impossible task of trying to discipline themselves.
