the speed of sleep

PEople always use the example of babies crying to alert their parents to the fact that they need food as an example of people's inherent selfishness, which is equated with sin.
First of all, being selfish is not a sin.
Secondly, babies don't have the mental capacity to understand what greed is and their attention span is too limited to retain that information if they could understand it.

Children don't take very long to embody traits that are man's downfall.  My 3 year old nephew leans on his own understanding far too often and as a result violates the commandment to honor his parents.  However, this 3y/o nephew doesn't understand how to avoid playing too rough with his 1.5 y/o brother to keep from killing him or seriously injuring him.  He also does not know how to read.  His comprehension skills have dramatically improved over the past year and I'm told he has comparatively very high intelligence.

The so-called Age of accountability is not a concrete thing.  People's 1st sin is always idolatry.  If you're not trying to avoid disobeying God it's because you're too focused on other things.  There will be a time when Joseph has enough understanding to avoid breaking any of the 10 Commandments but will he be aware enough of his Creator to do so?  Will he revere his Creator enough and appreciate Him enough to do so?

At 3, my nephew is fast approaching the age of accountability, I do think.  Is he there yet though?  I don't think so.

I was thinking about my sister's complaint about a chronological Bible that she was having negative feelings toward because, for example, it covers "the triumphant entry" four times in a row.  It's covered in all of the four Gospel accounts, so instead of chronicling it and moving on, it covers the triumphant entry and then covers it again.  The point is to include every last "letter" of God's Word without exception.  That's stupid.  The Bible is chronicled the way it is because God wanted it that way.  It makes sense as it is.  It covers everything you need to know in the order you need to know it.
If you want a timeline of The Bible's events, there's a way to offer that without re-arranging the chapters of The Bible.  The Bible is not written as a timeline.  It's written as nourishment for the soul.  God is not limited by time and space.  We need to look toward Heaven if we want to get there.  Looking at old bones is not going to accomplish anything.
