Jesus said, “Let your speech be Yes or No.” Matthew 5:37
Saying “Yes” without resentment, and saying “No” without regret is what Christian freedom looks like. Such freedom is beyond the law, as Paul and Luther so clearly point out. In other words, when we are acting from love, there is no law we must feel regret for breaking. And when we are acting from love, there is no law we need to feel resentment for obeying. In truth we need not moderate our “Yes” or “No” in order to fit in or not fit in—or in order to play it safe or not play it safe. All real options are permitted to Christian freedom.
Of course the laws are guidelines, often reflecting centuries of wisdom, but for your or my personal responses in each moment of our 21st century living, we have no absolute obligation to obey any law. We need to feel no resentment for obeying any law, or have regret in not obeying any law. We can be open to our essential freedom.
