“Walk a mile in my shoes” is an old proverb that has no root in scripture. It likely began as an American Indian saying about not judging until you have experienced what my moccasins are experiencing, but no one knows the origin. But it does make sense to withhold judgment of someone else until you fully understand their motives for what they did/said.
An important element in this is ’empathy’, or the ability to feel what the other person is feeling. Every Christian should practice the art of empathy. When a person is angry, find out why they’re angry. If a person is fearful, try to discover what the root of the fear is. Empathy will help you come alongside them so you can help them on the journey. And coming alongside them in their trouble is walking a mile in their shoes. Start walking.
