You are very correct my friend, the greatest love is the one that Jesus gave his life for us that we might be saved. I enjoyed reading from you, there are boundless sacrifices that comes with love; so if we say we love we should be ready to go extra miles for people. Love does not only involved happy moments but sad moments too, that is in the bible portion you have quoted says; love is long suffering, it doesn't lie, love is not boastful and so on. You have written well and I wish you success
