In his The Scandal of the Kingdom, Dallas Willard writes:
People can do good things and appear to be very good, but when opportunity arises, they may do whatever it takes to get what they want, even if they have to sin to do so. Character is not about what people do, but rather about what they would or could do given the opportunity. The opportunity reveals where their heart has been aimed all along.
Have you ever noticed this about yourself as opportunities come your way? Have you ever noticed it in others when they are offered significant opportunities? Is character consistent? Is it consistently good?
If you have the power to give someone an opportunity to do something significant, would you take their character into account?
