In everything you do, have integrity. This is perhaps the most important thing in life. It is essential not only for your personal reputation, but for the family whose name you bear and, most importantly, for the witness of Jesus Christ. So much is at stake and so much depends on living a life of integrity.
This morning, I had to fire someone because of a gross lack of integrity in their life that was spilling over into the workplace. I got to explain to the students at school that, while it was not the easiest or most convenient thing to do, it was the right thing to do. The integrity of our school, our church, ourselves, and the Lord Jesus Christ were all at stake in how we chose to handle the situation.
Situations will arise, and likely often, where you will have the opportunity to compromise your integrity. Don't do it. Never do it. Once you lose your integrity, everything else is lost. People cannot trust you and they will have no faith in you, and they will be justified in both.
Do the right thing. Even when it is uncomfortable, and even when it is much more difficult than doing the wrong thing. Always, always, always do the right thing. Live a life of integrity and be a person of integrity.
