Coincidence—as in an event (or something) that occurred (or exists) for no reason (or by accident, chance)—is non-sequitur and it is never a conclusion for anything, for it cannot conclude anything. For that reason nothing is mere coincidence. Many will deny this, but one can never prove this coincidence; it is like trying to prove that truth doesn't exist. Therefore everything happens for a reason, even if we do not know this reason. Note that there is no middle man here.
Coincidence, then, is shown to be a word used merely for one's convenience. It fills the gap in knowledge (though inappropriately) so as to maintain any disbelief the person may hold. It is not a word for anyone who seeks to know (the) truth, nor for one who seeks to remain in truth. For truth cannot be found within coincidence, as it follows from nothing. Therefore it cannot be said that life or existence as we know it bears no reason.
Since we know, then, that everything in this universe bears a reason for its existence, the reason for this universe cannot be of the universe itself. For this universe cannot give itself a reason for its own existence, only an external force can—the very thing that caused it to be. One might argue, then, that if there is no such thing as coincidence and therefore everything has a reason, what then does one say of God? However, eternal things do not have, nor need, a reason for their existence—they just are. And to say that God gives Himself a reason for His existence is itself illogical, for He would already be in existence before having given Himself a reason for His existence.
Reason, therefore, pre-exists the very thing it relates to; or, in other words, the cause of an event pre-exists the event itself. In order for something to be true there has to be an end, a conclusion, to it—for truth itself is a logical conclusion to a matter. The path on (of) an infinite line of creators, therefore, is illogical and can never be considered truth. Therefore we know that there can only be one true God, Creator, which is the Beginning (the Alpha) and will be the End (the Omega).
