It can be much more difficult to exercise character in leadership if you are in the wrong field, place or position in this life. If you have become frustrated and uncertain in your leadership you may say and do things that are not honest or forthright, for the purpose of protecting your position or keeping your insecurities from being exposed. If you are motivated not by your inherent purpose, but by other impulses, have a desire for fame, money and other such things; then you will want to do whatever it takes to achieve those ends and character will take a backseat.
My wife Arlene and I watch a television program called "The Profit". The program is based upon seeing potential in a business, upon the request of the owner/owners of the business. Watching this program, I have observed that his key focus is on integrity and honesty in business. These are Kingdom principles! Speaking of integrity, King Solomon stated it this way: "The righteous man walks in his integrity. His children are blessed after him". He also stated: "The integrity of the upright will guide them. But the perversity of the unfaithful will destroy them".
Now, the same principles apply to any arena of endeavor. If you know you couldn't have good character while pursuing a certain goal or working in a certain field, then you should cease pursuing that goal or vocation and find your true purpose. God will not give you a purpose that requires shady, unscrupulous behavior to accomplish. Don't let Satan pervert your purpose. God's purpose is always fulfilled in integrity and obedience to God's Word. You should pursue something that you can do with honesty as well as with integrity. Even when you are functioning according to your purpose, you still have to build and maintain your character. You can avoid some of the ethical pitfalls that spring from wrong motivations, boredom or apathy and the fear that others will learn your weaknesses.
Remember, your strongest defense is God's Constitution (God's Word).
Heaven and earth will pass away, but My Words will by no means pass away.
