Love

is a many-splendored thing according to a book, a movie, a song and a soap opera by that title. 

According to advertisements for the automobile brand, love is what makes a Subaru a Subaru. 

According to 1st John 4:8, God is love.

In the Japanese anime A Misanthrope Teaches a Class for Demi-Humans, love is what is sought by a character named Karin Ryuzaki.

Here is that show's plot as described by Wikipedia:

"Rei Hitoma, a reclusive man nearing thirty, has withdrawn from society after traumatic experiences dealing with human relationships. Seeking a quiet change of pace, he accepts a teaching position at a secluded all-girls school, only to discover that the institution's purpose is to educate demi-humans who wish to become fully human. Despite his aversion to people, Rei is tasked with instructing students who admire humans more than anyone else."

In the show, Mr. Hitoma meets Karin Ryuzaki when she is placed in his homeroom class at the start of his second year teaching at the school for demi-humans. Immediately upon their first meeting, Karin tells Mr. Hitoma that she loves him and that she wants to marry him.

On the day after, Mr. Hitoma has a private chat with Karin in order to set the needed boundary between the two. During the chat, Mr. Hitoma asks Karin why she allegedly loves him in particular.

She answers by describing what she witnessed the previous year when she saw Mr. Hitoma help another of his students named Sui Usami. 

Mr. Hitoma didn't help Sui with a school-related problem. He helped her with a personal problem that threatened to destroy the reason she was enrolled in the school in the first place. Whereas the school's principal offered a type of help that was safe, Mr. Hitoma understood that Sui needed the kind of help that was risky.

Karin witnessed how Mr. Hitoma helped Sui. He actually risked losing his job in order to aid Sui during the worst and most delicate moment in her life.

In John 15:13, Jesus says, "Greater love has no one than this: to lay down one’s life for one’s friends."

Mr. Hitoma didn't risk losing his life, but he did risk losing his job for Sui's sake. In short, Mr. Hitoma acted out the kind of love that Jesus mentions in John 15:13.

In the anime, Karin craves love. She wants to be cherished by a Human, which is why she wants to become a Human. So, when she saw Mr. Hitoma display godly love for a student, she decided that Mr. Hitoma was the kind of Human who should be her life-partner.

It is easy to claim that we are believers in Messiah Jesus, but if we make that claim, then we harm Jesus if we do not also display the kind of love that should make Jesus attractive to others, the kind of love that made Mr. Hitoma attractive to Karin.

I don't always succeed in displaying such love to members of my own family let alone to people I meet out in public.

For example, once I went into a pharmacy that I pass by whenever I travel to and from church services. While in the pharmacy, I spoke harshly to a pharmacy employee who was only doing his job. After I left, I realized the error of my action, and I felt guilt whenever I went into the pharmacy and saw the worker.

Finally, one Sunday morning before church, I went into the pharmacy to buy something, and I decided not to leave until I had confessed my sin to the employee and did what I could to make amends.

On another occasion, I sinned against my autistic son by being away from him at a time that was extremely important to him, and my sin was due to selfishness on my part. 

By doing what I did, I aggravated my physical disability to the point that I was in extreme physical pain, and I reacted to my son's distress by having extreme emotional pain. I was overwhelmed with so much pain and grief that I asked for a hug from two people whom I had just met. Shortly after, I sobbed as I drove home.

Devotion to Messiah Jesus should result in sorrow when one fails to love others the way that Jesus requires of those who claim to believe in him.
