The will of the Father is always unfolding around us--it is a continuous process--even at those times when it may seem to go contrary to OUR wills. ... Homo proponit, sed Deus disponit--Man proposes, but God in his own time (and way) disposes (and not always to our liking). But regardless, God's will is still ALWAYS being accomplished. Even 'Evil' is a part of that plan, for if not, then it means that God is neither omnipotent, nor omniscient.
Our only prayers, then, should be for our own acceptance and peace with God's will (especially when it seems so painful and distressing for us personally), not to ask that that will be changed to suit our own desires.
I know this may not be much comfort in time of stress and trial, but I also nonetheless believe it to be true. ... And I personally cannot do anything but speak the truth. I am incapable of hiding behind a convenient, comforting half-truth (or even outright untruth).
Having said that, though, I do wish only the very best for your friend, and for all such children of the Living Father who are simliarly distressed. God knows I have been there often enough myself. And can I then have no compassion for others who also suffer as I have? One cannot LOVE unless one has first SUFFERED.
I ask that the peace of the Father may find a place in your souls.
