The Fruit of the Mystery of the Visitation is Love of Neighbor.
This is sort of easy to understand. As the it is the second of the Great commandments and it is basically the Golden Rule of ages past. Do unto others as you would have done unto them, or however you want to phrase it is a common thread for all human kind. Both the religious and even the humanists of the world can live by this idea.
It would be awesome if everyone in the world could follow this rule, but this mean everyone and I am sure that some individuals like those in ISIS wouldn’t care for this one bit. If we could all try to love our neighbors a little more it would be a step into building the Kingdom here on earth and this is the mission for all humans.
