At first glance and perhaps first thought, practicing Jesus’ words here seems more or less easy. But on further thought it really isn’t. We can start on a surface level, for example simply being courteous to others, I think of strangers here, without being imposing. Even this attempt is as subjective as the understanding each person might have of it within many cultural influences.
But then we consider all of Jesus’ words, that somehow fulfilling such a rule sums up all the Law and the Prophets. Only a superficial reading of this might suppose that we can simply fulfill that by doing what we think is best. We certainly do have to make judgments all the time in life. The question here is whether or not we’re sufficiently steeped in scripture, what has been given to us by the Spirit, so that we can make a well informed judgment on what we really might want others to do to us, so that we can know what we should do to others. That is only the beginning of all the complexity inherent. What we need is wisdom. Something beyond ourselves, given to us from God in and through Jesus by the Spirit. But let’s not despise the small seemingly insignificant steps along the way in attempting to carry this out.
