A lady friend of mine who used to be our pastor's secretary had no patience for people who felt that Sacred Scripture was all good news -- "that it is all love and butterflies," as she impatiently characterized their thinking.
In fact, tucked-in among the "and God saw how good it was" characterizations of His creation in Genesis 1 and 2 are some ominous hints that maybe -- just maybe -- God's view of mankind was not so full of "love and butterflies."
In Genesis 1:24-31, note that as important is mankind is, in the scheme of things, there is no separate declaration, about mankind, "and God saw how good it was."
Instead, that declaration is reserved for the fullness of God's creation, mankind + the things needed for our salvation: God looked at everything He had made, and he found it very good." Genesis 1:31.
Additionally, on which day of creation was man created? Day Number 6, the Biblical number symbolizing evil.
Additionally, what was Adam made out of? Usually the Hebrew word for what God made man out of, aphar, is translated "clay." Much more commonly, aphar means "dust." "Dust" is a Biblical symbol for sin.
And then what was Eve made out of? Answer: "Sleeping stuff" -- sleeping Adam's rib. "Sleep" is the Biblical symbol for "death."
Any one of those, alone, are unpersuasive.
But all of them together, in the same few Bible chapters, give one pause.
And then there are the charming divinely-inspired words of Jeremiah 17:9...
The [human] heart [is] deceitful above all [things], and desperately wicked: who can know it?
Now, in light of the above, it is interesting to see what God built into the human body.
Supposedly, this is an unltrasound of our spinal column in cross section...
