1 Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:
2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.
The Abrahamic Covenant was a covenant between God and a man named Abram. God found a good and righteous man wh0m he could use for his purpose of creating a people for his name. Listed above in Genesis 12: 1-3 are the 5 promises God made to Abram. God would change Abram's name to Abraham in Genesis 17:3. The first promise that God made was to give Abraham a land. He told Abraham to get out of his country and away from his family, and he would show him a land. This land would eventually be the nation of Israel. Abraham did what God said, accept he brought his nephew Lot (Gen. 12:5). He was only suppose to bring his wife, this would set the tone for how things would go with God and the nation of Israel. Only two verses after the covenant was made and Abraham was already disobeying. The group left home to begin a life long journey.
The next promise was to make Abraham a great nation. God promised him that he and his wife would have a child. This was a bit of a problem for Abraham, because he was 75 and his wife Sarah, was barren. They had no children at this point. Abraham waited several years before he became impatient and decided to take matters into his own hands. He had a baby with Hagar his servant. The child's name was Ishmael. This was not what God intended and he was not happy about this disobedience. God was patient with Abraham though. (A side note, Ishmael would be the father Islam.) Eventually after 25 years, Sarah conceived at 90 years old. The babies name was Isaac. As Isaac grew his older brother Ishmael terrorized him. Sarah and God told Abraham to "cast out the bondwoman and her son". God did not acknowledge Ishmael and declared Isaac to be the seed (Gen. 21:12).
The next promise God made, was to bless Abraham and make his name great. God would grow a great nation out of Abraham (Israel). They would be very prosperous. This nation would show the world the power and blessings of God. They would have influence among other nations.
The next promise God made was to, bless them that bless you and curse them that curse you. This was a promise of protection and survival of this nation. God would directly watch over them and keep them safe from their enemies. God gave Abraham assurance that his descendants would be taken care of. This would also benefit any person or nation that blessed Israel. They would be rewarded for their effort. It would paint Israel in a positive light to all nations and show the awesome power of God. Ultimately God wanted to use Israel to show his power and blessings to the world. This will bring us to the next point.
The final promise of God is that through Abraham all the families of the earth will be blessed. This is the whole point of the covenant. God did not choose these people because they were better than everyone else, he chose them to be the light of the world. Through them the world could see the true and living God. Most importantly this nation would be the one God used to bring about the Messiah to forgive the sins of the world. God would do this twice. The first time, Christ was crucified and the message of salvation was brought to the world by a small group of Jews. The second time has yet to come. Jesus Christ will again return and establish his throne in Israel. This is why this covenant is so important, it promises Jesus Christ as the king of the world. The only way this is possible is by resurrecting the nation of Israel. When Israel was brought back, this put us back into the Abrahamic covenant. Not that it went away, it was just on hold. Now through Abrahams descendant the whole world will be blessed. I feel strongly that the Jesus will return very soon. Praise the Lord.
I hope this was a blessing to you and I will leave you with the gospel. You are saved and go to heaven by putting your faith in the death, burial, and, resurrection of the Lord Jesus Christ. It is the shed blood of Jesus Christ that washes away all sins, and not good works.
23 For all have sinned, and come short of the glory of God;
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
I Corinthians 15
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
