Worry is fear-spread-thin; and fear is the opposite of Love.
(Fear is, indeed, cast-out by Love - and the injunction Not to fear is almost a refrain in the New Testament.)
Yet we can, and many do, spend their entire conscious lives worrying; and if they accidentally stop worrying for a few moments, then they feel guilty - they apparently suppose that the world is being held-up by their worrying.
But this is evil - by which I mean to worry is to Be evil: to spend life worrying is evil, it is a state of sin.
Worry is (therefore) anti-Christian.
But what if I can't Help It! - what when can't help worrying?
Of course you can't help it, neither can I - but that doesn't stop worry being evil - it means we must repent the fact that we worry, instead of feeling guilty if we don't worry.
Worrying about stuff, being worried about 'other people'/ the environment/ poverty/ freedom/ global warming/ disease/ death... this doesn't make you a good person - but the opposite.
Because Fear is A Bad Thing, then it doesn't matter what you fear - choosing a worthy subject for your fears does not change fear into a virtue; any more than it would make resentment or spite into a virtue.
Re-naming fear as 'concern' does not make it good!
The false rationalisation is that Not to worry is to be Uncaring... You've heard this...
Hah! So, if somebody, somewhere, has had or might-have something bad happen to them - then we ought to worry about it! Yeah, right...
It is time for you to stop thinking you have a duty to worry; and instead think about your duty to Be Not Afraid.
