Our personal values drive our behaviors. However, sometimes our behaviors contradict our values. When we make conscious decisions that go against our values, we create challenges in our relationship with God and our relationship with people.
Luke 6:31 tells us to treat others the way we want to be treated. Sometimes we think, "this isn't hurting anyone, so, it's ok". We may say it's ok to lie to our spouse and say the shoes were on sale or keep the extra the cashier accidentally gives us as change...but we don't like it when it is done to us. We get upset when someone lies to us and we find out or when we don't get the $1 back we were supposed to get...we feel cheated. So, it never is ok to consciously do the wrong thing!
If you make a mistake, try to correct it. If you can't correct it, then work to not do it again. The key is to consistently work to please God and to be scripture in action. Trust God when the decision is difficult and goes against human opinion. It may not always be easy, but it is doable.
