A big problem in the modern spiritual life is the deficit of discernment - our inability to know Truth from Falsehood - to see-through deception.
This deficit is perfectly understandable, considering the weak and shallow nature of modern Christianity; yet it is devastating in this particular time and place, where evil walks in a multitude of disguises, and puts forth a kaleidoscope of temptations.
The spiritual life has mostly been eroded by softness, blurring, laxness - yet the alternative of strict 'ultra-correctness' (the unyielding observation of forms) is often not a solution, since it can too easily be impersonated, and too easily transforms from love to pride.
Perhaps the lack of discernment, and the consequent inability to hold the true middle way, is the single most important spiritual problem of all in the end times when lies come salted with truths, and purposive evil wears the cloak of virtue?
Perhaps if only we could recognise the path, then we would be able to tread it?
Perhaps it is discernment for which we should pray, even above all other gifts of Grace?
