God gave us minds and the power to make good choices. He put us on the earth, in the rough-and-tumble of this time in history, in all the particular circumstances of our particular lives. He put us here for one reason: so that we can grow into the saints He made us to be. We grow by learning and by making choices—learning the truth and choosing good over evil.
We human beings have a wonderful power: we have the power to act. Not “act” as in Charleton Heston, Eddie Murphy, Colin Firth, and Meryl Streep. I mean “act” as in: to do something, like shaking someone’s hand or making a pizza.
We do have an audience: God. He sees it all, and He knows all. He pulls for us always to do what is right. He sends us countless helps to avoid doing evil. He longs to reward us in the end for serving Him faithfully. But He respects our freedom enough that He will let us destroy ourselves forever by sin—if we so choose.
So we do not act alone: God sees, helps, loves. Also, we generally do not act alone as individual human beings, either. We participate in undertakings that involve groups large and small. Undertakings like: choosing friends in school, or working for a company, or supporting a candidate for public office, or investing our money.
This means that we bear ultimate responsibility not just for what we do individually, but also for what we choose to co-operate with.
