Backstory: God called Abram to leave his
country, his people and his father’s household and set out for his ‘promised
land’. God would bless Abram making him into a great nation with a great name. Moreover,
God would eventually bless the whole world through Abram (Genesis 12:1-3). Originally
God called Adam to multiply God’s images throughout the earth (1:28), and later
God restated that responsibility to Noah (9:1-2). Now God calls Abram out of idolatry
in Ur and promised him multiple descendants and homeland to bless ‘all peoples
or nations of the earth’. However, it’s now a decade or so later and Abram
remains childless and he still has no property.
1-6 In a vision the Lord tells Abram not to fear for the Lord was Abram’s shield,
and great reward. Abram is elderly and he’s been waiting on God for several
years. The Lord had promised Abram would be a ‘great nation’ through whom God
would bless the world. But, Abram was childless and his servant was his heir. Now
Abram’s in his 80’s having set out for Canaan when he was 75 years old. Abram
has no son, no land and now the Lord tells Abram that ‘a son coming from
Abram’s own body’ would be his heir. The Lord shows Abram the night sky and says
“count the stars if you can—so shall your offspring be.” Abram sees countless stars; beyond
number and he believes the promise and the Lord counts it to Abram as
righteousness.
7-21 The Lord reminds Abram how He brought Abram out of Ur of the Chaldeans and
having promised him the ‘Land of Canaan’. It’s been a number years now, so Abram
wants to know how he can be sure that he would possess the land. So the Lord tells
Abram to bring a heifer, a goat, a ram, with a dove and a pigeon. Without any further instruction, Abram knows
to cuts the animals in two and arranges the halves opposite each other. When
the ‘birds of prey’ come down on the carcasses, Abram drives them away. Then at
sunset Abram falls asleep, and a ‘dreadful darkness’ came over Abram. The Lord tells Abram how Abram’s
descendants would occupy their ‘promised land’ 400 years in the future.
So in this story God formalizes the
covenant he initiated with Abram in Genesis 12. The Lord confirms his ‘promises’
to give Abram multiple descendants and a homeland. However, Abram’s descendants
would go down to country not their own for 400 years and be enslaved (Gen.15:13-14).
Abram would rest with his ancestors and God would judge their oppressors. Abram's
descendants would possess Canaan, but the Amorites would face God’s judgment.
Now we know that Isaac, Abraham's promised
son, would have a son, Jacob. Jacob would be the father of the 12 tribes of
Israel. Jacob’s gifted son, Joseph, through a series of providential events would
become a ruler in Egypt and would preserve the Israelites through a time of
famine. However, after Joseph dies the Israelites become enslaved in Egypt.
Then God would call Moses to deliver them out of Egypt. Moses aid, Joshua,
would lead them in their conquest of Canaan when the sin of the Canaanites
tribes was ‘complete’ (after 400 years). So Abram's descendants would possess
the ‘Land of Canaan’ after a long delay because the sin of the Amorites was not
yet full (Gen.15:16).
The story depicts the long range purposed
of God. We see God’s long-suffering as He patiently waits over 400 years before
judging the ‘ungodly Canaanite tribes’. The various Canaanite tribes defiled
Canaan with their ‘idolatry and sexual deviant behaviors’. Therefore God justly expelled
them from Canaan (Leviticus 18, 18:25). Moreover, God gave them ample time to
turn from their ‘wicked ways’ but to no avail. Eventually, God told Joshua to “completely
destroy” them (Deuteronomy 20:17, Joshua 24:8). However, we must take note that
God said that what applied to the Canaanites would apply to the Israelites as
well.
