Thing is Church isn't really intimate enough to say it's a personal love of each person there, you don't really know the people at church that well, you know a surface level "they love Jesus, I love Jesus, so that means I love them" it's love that hinges on a single data point. It's kind of shallow and impersonal.
and I know myself I feel more like... tolerated at church rather than accepted. Being a single adult man in church is not the greatest context of being there.
as far as dealing with loneliness? I wish I knew, I struggle with this same thing.
I know I know, the holy spirit is with us.. but invisible.. intangible, can't give you a hug when you need one.
I mean, Paul writes in his letters to greet each other with a holy kiss but ask yourself, are churches really that intimate? Most I've seen is handshakes, which is a distancing gesture, designed to limit intimacy, keep at arm's length.
Then you sit in the pew.... alone, while everyone is with their families.
