In the gospels we read how Jesus was always around people. He had a life full of relationships. Always talking, drinking, eating, relaxing; sometimes entertaining his guests and sometimes being entertained by them. What is fascinating is that these relationships were not based on these people holding to the same theology and doctrines as Jesus did. In fact, it's safe to say that none of them believed like Jesus did. Yet he was always in the company of people, and these connections became very deep and heartfelt relationships.
It seems to me that if we truly want a life full of loving relationships, we need to care less about what doctrines or world views people believe and more about the actual person. When we let our love for others be what unites us, we begin to have a life full of meaningful relationships.
