and at the same time, I can almost visibly tell if they're without it.
It's just from studying both sides on the spectrum, and being on both sides of the spectrum: joyful, and joyless. It's not seeing auras or reading minds, it's seeing body language; realizing how people talk, how people act. You can tell Christians with such joy in their hearts just have this glow about them; they smile more, they're genuine, they're true, pure. Even if they're troubled, or sad, there's a light of hope there for them that the lost don't seem to have yet..
Joyless people are just so grim and seem almost hopeless. They have a way of masking bitterness and joylessness, with witty, dirty or sarcastic comments, or a facade that's as thick as mud. They think they have a security in their life, but they truly don't. They seem to shrug off any sort of spiritual or eternal type conversation, or they try to have an answer for everything to seem like they're not concerned, not worried.
Joyful people don't have worry or panic in the same sense that joyless people do.
Joyful people know where their eternity lies.
Just some musings on the idea. I just feel like I can just sense the joylessness in some people; whether they show it, or not.
