It was C.S. Lewis, himself a possessor of a strong bond with fellow author J.R.R. Tolkien that helped from both men's writing and character, who wrote most poignantly about the current condition of friendship or "philia."
What love motivated God to create human beings in the first place? A love for the other. The trinity is a mysterious and inexplicable truth. One thing we can definitely know is that if God lives in community and has lived in the community of Father, Son, and Holy Spirit from eternity to eternity and God is Love, then God is motivated to create out of His love and in conjunction with His character as developed by the eternal connections that bind the three members of the Trinity into one God.
What love motivated God to forgive His creation even as it rejected Him and severed the community that existed between God and man? The love of a friend. The same love that Jonathan showed to David when he went to his father, King Saul, and pleaded for David's life. He convinces the king to be merciful and spare David's life.
Saul told his son Jonathan and all the attendants to kill David. But Jonathan had taken a great liking to David and warned him, “My father Saul is looking for a chance to kill you. Be on your guard tomorrow morning; go into hiding and stay there. I will go out and stand with my father in the field where you are. I’ll speak to him about you and will tell you what I find out.”
Jonathan spoke well of David to Saul his father and said to him, “Let not the king do wrong to his servant David; he has not wronged you, and what he has done has benefited you greatly. He took his life in his hands when he killed the Philistine. The LORD won a great victory for all Israel, and you saw it and were glad. Why then would you do wrong to an innocent man like David by killing him for no reason?”
Saul listened to Jonathan and took this oath: “As surely as the LORD lives, David will not be put to death.”
So Jonathan called David and told him the whole conversation. He brought him to Saul, and David was with Saul as before.
