Everything Happens For A Reason -- REALLY?

In the last several weeks I have heard, this somewhat innocuous statement -- many times:

Now, this idea is often communicated by people, who at least appear to be expressing this in a less than religious context.  It comes across as a truism that is widely accepted by a diverse group of people. Now I am a unapologetic Christian.  Somewhere along the line, every Christian has to believe in the sovereign, providence of God. To  say that is to say, "Everything happens for a reason."

This maxim in the context of Christianity affirms the Biblical position that we are all dependent upon a personal, creature God, who ". . . doth uphold, direct dispose, and govern all creatures, actions, and things, from the greatest even to the least, by his most wise and holy providence, according to his infallible foreknowledge, and the free and immutable counsel of his own will, to the praise of the glory of his wisdom, power, justice, goodness, and mercy." (Westminster Confession of Faith)

My question is this: to what force or being does one who does not believe in God attribute such power that they can say with confidence that everything happens for a reason.  Of course to be cynical we could say that things happen for a reason does not necessarily mean that such an event occurs with particular significance. To say something happens is just an acknowledgment of reality. But the context that many use this is that things happen for reasons that bring worth, validation and affirmation of what they just experienced.  So this begs the question.  If you do not believe in God as the Bible portrays Him, to whom do you attribute such power?

To fail to believe in the sovereign God of the Bible is to generally believe in random order or at least a self-generating cosmos.  To believe that things happen for a purpose dismisses the former and gives incredible super-powers to a non-rational entity like the cosmos.

I can only imagine that non-Christians seek to borrow equity from the Christian faith in order to promote an idea that everything happens for a reason.

Is this not the height of hypocrisy?  A consistent unbeliever must hold to a randomness to life to the degree that when something happens, the best that can be said, is that: Life happens. That's it!

“Who can speak and have it happen if the Lord has not decreed it? Is it not from the mouth of the Most High that both calamities and good things come?” (Lamentations 3:37–38, NIV).
