"Paul, looking intently at the council, said, 'Brethren, I have lived my life with a perfectly good conscience before God up to this day.'  The high priest Ananias commanded those standing beside him to strike him on the mouth.  Then Paul said to him, 'God is going to strike you, you whitewashed wall!  Do you sit to try me according to the Law, and in violation of the Law order me to be struck?'  But the bystanders said, 'Do you revile God's high priest?'  And Paul said, 'I was not aware, brethren, that he was high priest; for it is written, 'You shall not speak evil  of a ruler of your people.'"

Paul makes a mistake here.  He condemns a leader of the people.

Now something amazing happens:  He takes responsibility for his mistake.  He shows where his reasoning comes from - it comes from scripture.  Paul understands that he cannot ONLY use the word of God to how needed growth in other.  The Word of God must also be used to show where Paul has to grow.

If you want to be a man of God, show other people where they must grow as you hold the Bible next to them.  But first, hold the Bible next to yourself -you must lead in growth.
