I think you may have misunderstood what I wrote: I wasn't saying I have actual love for 6 billion people, as that would be pretty foolish.
Yep, sounded foolish to me.

I struggle to manage the 20 I mentioned, let alone 6 billion.
However, I am happy to read your further comments, and to thank you for your empathy.
But I do think some people on this thread rather underestimate how difficult love can be. To paraphrase Christ, it is easy enough to love those who love us, because even tax collectors can do that.

What is truly difficult is to maintain that love in the face of abuse, rejection, ill health, deprivation, poverty; you name it. Some of us have this challenge, others are more fortunate. But it is certainly not easy.
Fwiw, I do not differentiate between different kinds of love, because that is an unnecessary complication of a simple enough emotion. As I see it, as long as my love for anyone else is focussed on meeting their emotional, spiritual or physical needs, whichever is appropriate to the relationship, then the expression of that love may differ, depending on whether it is a partner, child, friend or whoever, but the love itself is the same thing.
My love is about enabling others to grow spiritually. It can never be about me getting anything from someone else that they are not willing to give, and therefore cannot ever be abusive. And all love, which is sacrificial in this way, is of God and is part of his love.
When it turns instead into me and my needs, then it is no longer love, but something else. And as it is no longer love, it is no longer of God.
Hence no need for the (to me) rather artificial concept of agape. It is all love. But if others prefer other words, then that is fine and dandy.
And, so that the point does not get lost, when Christ's love is revealed in the world, then Christ himself is present, and that does a far better job of promoting our faith than any theology or even quoting Scripture.
As for seeking anything from God, I am long past that. All I do now is to pray "Thy will be done" and the Kyrie. And then do the next thing.
God forbid that anyone here who does not know what I am talking about, should ever have to come to understand. And those who do understand, God be with you.
