I came across the following in a periodical:
Most people make integrity synonymous with honesty, but integrity has a finer point. The root word for integrity is “integer,” which implies singleness, unity, something not divided, consistency, and by extension, reliability and trustworthiness – in everything.
A person of integrity is an honest person. He does not lie, steal, cheat, or take unfair advantage of others. The true follower of Christ has little problem with these major issues. Even the best of us, however, are sometimes careless about our integrity in little things. It is important that we maintain our integrity at every level. It is the “little foxes that spoil the vines” (Song of Solomon 2:15).
The person of integrity presents the same face every time and in every situation. In contrast, a hypocrite presents a different face to different people. Even a little two-facedness violates scriptural principles and undermines our integrity. Those who observe this behavior lost the ability to trust our “face.”
It would seem that consistency is as much a part of integrity as honesty is. Without honesty, integrity is impossible. Without consistency though, we can fool ourselves into thinking we are people of integrity because we are ‘telling the truth’ even when we tell the truth from different perspectives.
The person of integrity speaks the same message regardless of who they are speaking to.
