The nation of Israel represents the people that God chose to be His very own which started with a promise to the patriarch Abraham.

In Genesis 11, we find Abraham, originally named Abram, descended nine generations from Shem (son of Noah). When Abraham was around 70 years old, he was called by God to leave his country in Mesopotamia to go to a land that God promised him where He would make of him a great nation. This promise is known as the Abrahamic Covenant.

Now the LORD said to Abram, “Go from your country and your kindred and your father’s house to the land that I will show you. And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.”
Genesis 12:1-3

So, Abraham believed God and left the land of Ur. Abraham followed God through many lands and trials because he trusted God for the promise. God reiterated His promise and told him he would be called Abraham which means “father of many nations.” 

When Abram was ninety-nine years old the LORD appeared to Abram and said to him, "I am God Almighty; walk before me, and be blameless, that I may make my covenant between me and you, and may multiply you greatly." Then Abram fell on his face. And God said to him, “Behold, my covenant is with you, and you shall be the father of a multitude of nations. No longer shall your name be called Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations. I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you.  And I will establish my covenant between me and you and your offspring after you and throughout their generations for an everlasting covenant, to be God to you and to your offspring after you. And I will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and I will be their God.”  
Genesis 17:1-8

Because Abraham and his wife Sarah, originally named Sarai, were very old, they had a difficult time believing that God could give them a child. Instead of trusting God, they decided to “help” Him. Sarah gave her Egyptian handmade, Hagar, to Abraham so that she could give them a child. Hagar conceived through Abraham, and a son was born whom they named Ishmael. Abraham loved Ishmael very much, but soon trouble started between Sarah and Hagar. Arrogance and jealousy between the two women ensued because Hagar looked down upon Sarah who was without her own child. This was difficult for Abraham, but he held on to Ishmael as if he would be his covenant heir.

However, Ishmael was not God’s choice, as Abraham had hoped. God said that He would provide through Sarah the promised son who would be named Isaac.

And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name. I will bless her, and she shall become nations; kings of peoples shall come from her.” Then Abraham fell on his face and laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” And Abraham said to God, “Oh that Ishmael might live before you!” God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.” 
Genesis 17:15-20

As God promised, Sarah became pregnant in her old age and gave birth to Isaac, the covenant heir. Abraham was overjoyed with Isaac and still loved Ishmael very much. As Isaac grew, trouble in the family started again—this time between Ishmael and Isaac. Ishmael made fun of Isaac and Sarah became enraged, telling Abraham to get rid of Hagar and her son. Ishmael was Abraham’s first son and he was very displeased by this reaction from Sarah.

God appeared to Abraham and assured him that Ishmael would be okay and that he should send him away with his mother. 

But God said to Abraham, “Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. And I will make a nation of the son of the slave woman also, because he is your offspring.” So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wondered in the wilderness of Beersheba. 
Genesis 21:12-14

Why did God make a covenant with Abraham through Isaac?

From the beginning of time, God had a plan for eternal redemption through the bloodline of Abraham, Isaac, and Jacob. These patriarchs are through whom Jesus was born. Our heavenly Father wanted the Israelites to be separated physically and spiritually from the other nations that worshiped false gods and performed ungodly practices. God called the Israelites to be righteous and to follow His ways which He gave to them in the form of laws.

When you come into the land that the LORD your God is giving you, you shall not learn to follow the abominable practices of those nations. There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the LORD. And because of these abominations the LORD your God is driving them out before you. You shall be blameless before the LORD your God, for these nations, which you are about to dispossess, listen to fortune-tellers and to diviners. But as for you, the LORD your God has not allowed you to do this. 
Deuteronomy 18:9-14

Does this mean that the Israelites always followed God’s laws?

No.

The Israelites would sin against God time and time again, but God was faithful to His word, forgave the Israelites, and vowed to bring His promise to fulfillment until the end of time here on earth.

Join me next week for the next part of this blog post where we will focus on the continued lineage of Jesus Christ through the nation of Israel.

May God bless you as you seek His truth for your life.
