One thing that God offers is feedback from an all-inclusive point of view without prejudice. We only see a small part of other people and overlook what others see in us. We filter what we do through our whole experience and we use that same filter when we look at what other people do. Other people use a different “life experience” filter than we do so they see things that we do not.
By building relationships with others we can begin to learn how they see us and we see them with more understanding because our filters begin to have shared points of reference. I think that God wants us to get to know people deeply because by seeing each other clearer we can help one another better. This knowledge and common experience in turn helps us to be more like He originally made us to be.
