Stewardship requires one predominant trait, that being faithfulness. People are gifted with many assorted skill sets requiring varying degrees of expertise. Yet, stewardship demands only a single element—faithfulness. The master of the house can teach his steward how to think ahead or how to deal with problems and even problem people, but the master cannot teach faithfulness. A wise master knows that his greatest need in a steward is faithfulness (Luke 12:42). In like manner, believers, as stewards of God, may be inadequately qualified for every needed task, but the importance of faithfulness must never be underestimated. No man can be a good steward if he lacks faithfulness.
The context of our passage speaks of judgment against Jerusalem and Judah. In this judgment the Lord vowed to remove much of the strength of the land. He promised to remove the mighty man and the man of war, the judge and the prophet, the honourable man and the counseller. The removal of these people would certainly weaken any city, town, or nation. Yet, it is in the midst of this list that the Lord included the prudent. Apparently, the prudent are the strength of any people just as much as their great warriors and judges. When all things are considered, this makes perfect sense. Those who are prudent make decisions that stabilize any people and provide future stability as well.
