So Poets write poems about love.
Musicians write songs about love.
Christians attempt to tell about the love for Jesus that is placed in their hearts by the Holy Spirit. But it is very difficult to express this emotion and this experience in words. A person can only know about this love through experiencing it. One can read and learn about it through great literature, but in all reality it is the experience that teaches us best. It is an experience with a Teacher, Leader, and Guide who demonstrates His love through a personal relationship with Him via His Holy Spirit.
