Week 10

Memory Verse: Isaiah 60:1-3

Reading #1: Genesis 15:7-16

Questions: Why do you think it was so much easier for a childless old man to believe that he would have offspring as numerous as the stars than to believe he would actually possess the land he occupied?  What role does Abraham play in the covenant making process beginning in verse12?  What does the Lord warn will happen to Abraham’s descendants as “a dreadful and great darkness” falls upon him? 

Reading #2: Exodus 10:21-29

Questions: What plague falls on the land of Egypt where Abraham’s descendants are enslaved?  What conditions are the Israelites experiencing in their corner of the land?

Reading #3:Psalm 18

Questions: In verse 6, how is David’s situation similar to that of the enslaved Israelites?  In verse 9, what accompanied God as He came down to rescue David?

Reading #4: Luke 23:44-49

Psalms and Hymns

Begin, My Tongue, Some Heavenly Theme “His very word of grace is strong as that which built the skies; The voice that rolls the stars a long speaks all the promises.”

Rejoice, Ye Pure in Heart  “Still lift your standard high, still march in firm array; As warriors through the darkness toil till dawns the golden day.”

Friday Factoid Week 9

Click here for a Flashback to what we were learning in our Hawaiian homeschool 6 years ago this week.

And click here for another Flashback that has to do with today’s topic.

Teacher’s Two-Cents

I haven’t added my two-cents to a Friday Factoid for a long time, so I’m doing one now and also giving the boys a break since you have 2 Flashbacks to nibble on and they’ve had a crazy busy week.

So I want to add my two-cents to the second Flashback above about the magnetosphere and the auroras it causes and this time my two-cents comes straight out of the bank of Job.

“Hear this, O Job; stop and consider the wondrous works of God . . . Can you, like Him, spread out the skies, hard as a cast metal mirror? . . . And now no one looks on the light when it is bright in the skies, when the wind has passed and cleared them. Out of the north comes golden splendor; God is clothed in awesome majesty.”

Job 37:14-22

Job is one of my favorite books in the Bible because I’m always amazed at the depth of scientific knowledge people of his time had and the conclusions they came to about God through what they observed in nature. They truly believed God made Himself known through creation.

The passage quoted above is a great example of that. It might sound very primitive and ignorant to our ears to hear an ancient person describe the sky as “hard as a cast metal mirror.” But when you think about the earth’s magnetosphere, that description actually makes a lot of sense!

The entire earth has a magnetic field surrounding it and its job is to pull harmful particles produced by solar winds away from the earth or reflect them back toward the sun. Sounds a bit like a mirror, right? The sky may not be hard as a cast metal mirror but it certainly has the reflective, metallic-like properties of one.

And what about that light people of Job’s day seemed afraid to look upon when it shone brightly after the winds cleared the skies? Where did that golden splendor come from? “Out of the north!” Sounds a little like the Northern Lights, the Aurora Borealis, doesn’t it?

And do you know what causes those auroras? The presence of that reflective magnetosphere of course! Some of those harmful particles from the solar winds get trapped in the magnetic field and crash into our atmospheric gases causing a beautiful light show.

Events like those should do nothing less than inspire us, like Job’s friend, to “Stop and consider the wondrous works of God.” He is indeed, making Himself known through them!

Devo 9

“Look toward heaven, and number the stars, if you are able to number them. Then he said to him, ‘So shall your offspring be.’  And he believed the Lord, and He counted it to him as righteousness.”  Genesis 15:5,6

Just how many stars are there?  That thought had to have crossed Abraham’s mind, just as it has your own, I’m sure.  But we don’t have any record in scripture of him ever asking and certainly nothing to give us a quantitative answer.  This childless old man is simply told that as the stars are innumerable so would his offspring be innumerable.  And he believed God.  

Well guess what.  Several thousand years later, the stars are still innumerable and so are Abraham’s descendants.  You’d think with all our advances in technology we’d at least be able to count the stars, right?  But no, we’re actually not much closer to an accurate number than Abraham would have been.  You could try using a service like “Ask an Astronomer” offered by Cornell University.  “How many stars are in the universe?” you ask, and someone like David Kornreich, who founded the program, would be forced to answer back, “I don’t know, because I don’t know if the universe is infinitely large or not.”  Well, that’s not a good start, is it?  So we’re a bit stuck already because we don’t even know the scope of what’s containing the stars.

So what if we started small and worked our way out?  Since stars seem to be clustered in galaxies, what if we started by counting the stars in our own galaxy and then multiplied that number by the number of known galaxies?  Well, there we go getting stuck again.  The fact is, we don’t even know how many stars are in our own galaxy.  Estimates run between 100 billion and 200 billion stars in the Milky Way, but good grief, that leaves a lot of wiggle room!  But we’ll go with what we’ve got.

Now, Mr. Astronomer, “How many galaxies are there?”  “About 10 Trillion,” says Kornreich.  Of course, that is a very rough estimate, because of course we don’t even know how big the universe is, right?  But the Hubble Space Telescope really helped give us a glimpse as to the shocking number of galaxies beyond our field of vision.  Focusing in on tiny dark areas of the sky, images reveal thousands upon thousands of galaxies per area.  So it takes a lot of creative counting to come up with the 1 septillion stars that Kornreich estimates.  That’s a 1 with 24 zeros after it.  It looks like this if you’re wondering: 1,000,000,000,000,000,000,000,000.

But really, we just don’t know.  We would probably do well just to believe God, like Abraham did, since Psalm 147:4 says that not only has God numbered them, He’s named them as well.

Anyway, it’s an awful lot of offspring being promised to a childless old man. Hebrews 11:12, says, “Therefore from one man, and him as good as dead, were born descendants as many as the stars of heaven and  as many as the innumerable grains of sand by the seashore.”  

That sounds pretty wonderful, but for the man called to lead a good chunk of those descendants out of their enslavement in Egypt, it was a bit overwhelming.  Innumerable descendants is one thing, but innumerable whining, complaining, bickering rebellious descendants is another thing entirely.  In Deuteronomy 1:9-12, Moses complains, that sure, the Lord had multiplied the Israelites, and they were indeed “as numerous as the stars of heaven,” but “how can I bear by myself the weight and burden of you and your strife?”

And what’s God to do with such a mass of rebellious children?  Later in Deuteronomy 28:58-63

He instructs them to be careful to “do all the words of the law that are written in this book that you may fear this glorious and awesome name, the Lord your God.”  Otherwise, he warns,

“Whereas you were numerous as the stars of heaven, you shall be left few in number, because you did not obey the voice of the Lord your God.  And as the Lord took delight in doing you good and multiplying you, so the Lord will take delight in bringing ruin upon you and destroying you.”

Whoa.  Why would the Lord take delight in destroying His own chosen ones?  That’s a side of His divine nature that makes us rather uncomfortable.  But think of it friend!  If the Lord didn’t delight in His own justice there would be no cross!  Isaiah 53:10 says “it was the will of the Lord,” or “it pleased the Lord” to crush Christ.  Why?  It was for you and me!  Jesus bore OUR sins, He carried OUR sorrows, He was pierced for OUR transgressions, He was crushed for OUR iniquities, the chastisement that brought OUR peace was put on Him, His wounds bought OUR healing, it was on Jesus that the Lord was pleased to lay OUR iniquity.  

We may not like the sound of the Lord delighting to show justice, but the Lord delights in whatever brings Him glory.  It brought Him glory to give a childless old man descendants as numerous as the stars.  And it brought Him glory to crush the One who spoke the stars into existence.  And it brings Him glory when we, like a man as good as dead, believe His promises and trust Him, delight-filled justice and all.
