Through the friendship between David and Jonathan (Saul's son), we get a clear picture of spiritual friendship. Each man was loyal to God first, and this allowed them the ability to develop loyalty to one another knowing that they each desired to follow God. Jonathan knew that it was God's will for David to one day be king instead of him, despite being the sitting prince. He was determined to see God's will established even at his own expense. Though his father was jealous of David, Jonathan chose to love David as he loved himself, forsaking family and the throne.
