Do your relationships simply serve earthly purposes? Or do you think they have spiritual value?
Certainly we learn from others. Certainly we learn at least something from every relationship. And it's not far-fetched to imagine that if angels were watching they would see each of our relationships as a teaching/learning device.
Quoted below is how Jesus Christ states this in his modern revelation for the 21st century, A Course in Miracles. To understand Jesus, think of yourself in terms of the ancient language Jesus uses as "a Child of God" or a "teacher of God."
"Each teaching-learning situation involves a different relationship at the beginning, although the ultimate goal is always the same; to make of the relationship a holy relationship, in which both can look upon the Son of God as sinless. There is no one from whom a teacher of God cannot learn, so there is no one whom he cannot teach. However, from a practical point of view he cannot meet everyone, nor can everyone find him. Therefore, the plan includes very specific contacts to be made for each teacher of God. There are no accidents in salvation. Those who are to meet will meet, because together they have the potential for a holy relationship. They are ready for each other."
The first level of relationships Jesus mentions are seemingly superficial encounters.
The second level of relationships, according to Jesus, are situations in which people come together for finite periods of time, engage in a relatively intense teaching/learning relationship, then separate.
Finally, Jesus discusses the third level of relationships, which is lifelong.
"The third level of teaching occurs in relationships which, once they are formed, are lifelong. These are teaching-learning situations in which each person is given a chosen learning partner who presents him with unlimited opportunities for learning. These relationships are generally few, because their existence implies that those involved have reached a stage simultaneously in which the teaching-learning balance is actually perfect. This does not mean that they necessarily recognize this; in fact, they generally do not. They may even be quite hostile to each other for some time, and perhaps for life. Yet should they decide to learn it, the perfect lesson is before them and can be learned. And if they decide to learn that lesson, they become the saviors of the teachers who falter and may even seem to fail. No teacher of God can fail to find the Help he needs."
