Why does anything exist ... why not nothing?

He is the image of the invisible God , the firstborn of all creation: for by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones, or dominions, or rulers, or authorities—all things have been created through Him and for Him. He is before all things, and in Him all things hold together. He is also the head of the body, the church; and He is the beginning, the firstborn from the dead, so that He Himself will come to have first place in everything. For it was the Father’s good pleasure for all the fullness to dwell in Him. - Colossians 1:15

What is “Love”?

Love means many things to many people. Sometimes it is significant and sometimes it is meaningless. To the ancient Greeks there were 8 words that all translated to “love.” These 8 words were Agape, Phileo, Storge, Mania, Ludus, Pragma, Philautia and Eros.
Eros is the word where we get the term erotic. It is a sexual, romantic love. It is the one we most often are thinking when we say or ask “Do you love me” or “I love you.”
Storge is the love that is bonded by family. The love a mother has for her child or the love between siblings
Mania Is obsession. A love that that reaches the point of madness.
Philautia is self-esteem (good) or hubris (bad). It is how we love ourselves.
Pragma is a love based on obligation or logic. This business like love is seen in relationships where practicality takes precedence over sex and romance. Or love of country or for a team.
Ludus is love involving play. Noncommital such as flirting or casual sex.
Phileo is the type of love that involves friendship. Love that isn’t based on physical attraction.
Agape is the kind of love that is felt by a person willing to do anything for another, including sacrificing themselves, without expecting anything in return.
