Why not to those who need it ?
He - according to the theory - gives them the means to do so: but does not gives these means to anybody else; most of us are left in the lurch, to fend for ourselves, while he pampers his favourites
Which is nice for them, granted; but pretty hard on us. Why are we, who are in such great need, left to fend for ourselves ?
That last detail is one of the cruellest demands of all. It is grossly unrealistic - what on earth is the point of trying to be what one never could be in a billion years
?
Holiness AFAICS is something for which some people have a talent; much as some have a talent for drawing, or languages, or music, or sports, or whatever it may be. Some people are Leonardos or Michelangelos for being holy, others are second-raters: & some of us are nowhere, & know it.

Not everyone can be a Handel - some can’t play an instrument at all: it would be the height of cruelty & silliness to require those with no musical talent to play an instrument. Yet to require holiness of all Christians, does that, only more so

To imagine one can be a Saint is sheer self-deception, & a recipe for despair. Mediocrity may not be very heroic, but it’s better to be mediocre & to do something useful with one’s life, than to soar too near the sun, come unstuck, & crash horribly.
God doesn’t answer prayer - not unless one is a very privileged person: an ecstatic, a visionary, a nun; that sort. Most of us have to make do with second-best. The fact is, prayer to the Tooth Fairy would be equally productive & useful. The real problem is that the doctrine of prayer encourages false hopes: & that is appallingly cruel

The seemingly cast-iron promises in the Bible can always be “got round” - the result ? God obviously does not mean what he says - & that means he is the greatest snake-oil salesman & deceiver of all.

That is wicked, or nothing is.
