1 Corinthians 13:4-5 says "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs."
Here is a video clip I've just watched, shared by a friend in Facebook. It is about a girl who had dated a guy for 10 months before he met with an accident that left him brain damaged and unable to fend for himself. Earlier, he had plans to marry her. So despite his condition, she got married to him. See true love in action: http://www.godvine.com/The-Story-of-Ian-and-Larissa-Shows-Unbelievable-True-Love-1518.html
Think: is true love only to be demonstrated by extreme adversity? I don't think so. IF the man in the video had fully recovered from his accident, I bet that the woman would still be demonstrating true love to her man, simply because she is capable of such love. The video would not have been made then. And somewhere in the world, this one couple would be living a life of unbelievable true love.
Most of us are fortunate enough not to be put through such a test. Yet without this difficult test, many already fail before sitting for the "exam"! Paraphrasing 1 Cor 13:4-7 in the negative, this is what is happening in many of today's failed or frail marriages:
Non-true love is impatient, non-true love is unkind. It envies, it boasts, it is proud. It dishonors others, it is self-seeking, it is easily angered, it keeps records of wrongs.
(You don't need to marry a quadriplegic to show true love to the one you marry!)
