I love Andrew Tozer's writings, and drink them deeply -- a true refreshment and strengthening for the soul.
Here is an excerpt from The Root of Righteousness on receiving admonition, which is, in itself, a spiritual discipline:
Those who have already entered the state where they can no longer receive admonition are not likely to profit by this warning. After a man has gone over the precipice there is not much you can do for him; but we can place markers along the way to prevent the next traveler from going over. Here are a few:
1. Don't defend your church or your organization against criticism. If the criticism is false it can do no harm. If it is true you need to hear it and do something about it.
2. Be concerned not with what you have accomplished but over what you might have accomplished if you had followed the Lord completely. It is better to say (and feel), "We are unprofitable servants we have done that which was our duty to do."
3. When reproved, pay no attention to the source. Do not ask whether it is a friend or an enemy that reproves you. An enemy is often of greater value to you than a friend because he is not influenced by sympathy.
4. Keep your heart open to the correction of the Lord and be ready to receive His chastisement regardless of who holds the whip. The great saints all learned to take a licking gracefully - and that may be one reason why they were great saints.
