Love is ....
The gospel of John and the letters say GOD IS LOVE
So in truth you are asking if God exists...
1cor 13: 4 Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up;
5 does not behave rudely, does not seek its own, is not provoked, thinks no evil;
6 does not rejoice in iniquity, but rejoices in the truth;
7 bears all things, believes all things, hopes all things, endures all things.
8 Love never fails.
Means that love is not only carnal ,could be filial or should serve all these people or is agape love !! the God kind of love!!
I know i will be marked negatively but I just don't care as long as you have got the answers for your questions.
