what does assumation do?

Assumation.
The act of assuming; believing and speaking on what is not yet knowledge to yourself.

So you may say that assumation is not a word. Judging by the fact that the squigley red line appears below it verifies what you say is right...I guess. But to me assumation is a word in my vocabulary, not because I like making up words to fit a rhyme like Dr.Suess but because I've come to yell out the good news. Assumation is the preacher at your local street corner yelling "Sinner!" out of Romans 1:29-32 and not bothering to read the very next verse, he just assumes it'll say, "You're going to hell."
Or like reading the Old Testament without the New....how can it be old unless something has replaced it.
And how can you know the importance of the New if you don't know how different it is from the Old?
Assumation is believing I won't love you because I call myself a Christian and so does your drunk and iced out ex-friend who decided to hate you after they "repented".
Assumation is allowing those doubting quotation marks to surround the word repented.

Who am I? To decide that I know enough to take the next step. Next breath. To blink one more time.
Trust that that next step, breath, blink won't lead me to my destruction, but in whom do I place that trust?
In myself? I don't know.
Whether that next stair is waterlogged and can't hold one more pound over 114.
Whether that mist in the air is really freshening the air or destroying the delicate twin organs in my one and only body called my lungs.
Whether that split second that I close my eyes would've been the split second I would have needed to react, and save my life if they were open.

I just assume that I'll live. That every one on this planet is doing his or her best job of living and putting each foot in front of the last towards living even longer. Whether your sight is near or far, committed to this world or the eternal.

-Tangent-
So why waste your assumation on believing that I would write disrespectfully to you. Or that I'd open-eyed prove myself to be a contradiction in the largest of ways. Or that I'd allow others to vandalize my property.
-End Tangent-

Why do we waste assumation, a verb that we use every moment to keep us walking foot in front of the last, on something as unwise and immature as to judge one another.

Tell me the justification.
