The fifth principle of our Judeo-Christian heritage is revealed in Genesis 12, Genesis 15, and Galatians 3.

Genesis 12:1-3 (NKJV)
1 Now the Lord had said to Abram: “Get out of your country, from your family and from your father’s house, to a land that I will show you.
2 I will make you a great nation; I will bless you and make your name great; and you shall be a blessing.
3 I will bless those who bless you, and I will curse him who curses you; and in you all the families of the earth shall be blessed.”

The Book of Genesis records the story of God making a covenant with Abraham.  The basis of that covenant was that if Abraham would believe God, God would bless him with many descendents, a nation of people now known as Israel.  Throughout the Bible, when ancient Israel had a king who reverenced God and held God’s Word in high esteem, the nation prospered.  When they had a bad king, life within the nation was full of misery.

Genesis 15:5-6 (NKJV)
5 Then He brought him outside and said, “Look now toward heaven, and count the stars if you are able to number them.”  And He said to him, “So shall your descendants be.”
6 And he believed in the Lord, and He accounted it to him for righteousness.

The application for us today is that during this dispensation (at this point in history), God is relating to the human race in light of the new covenant and according to who we are in Christ.  This is the Gospel, which was preached to Abraham and is confirmed in the NT book of Galatians.

Galatians 3:7-9 (NKJV)
7 Therefore know that only those who are of faith are sons of Abraham.
8 And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.”
9 So then those who are of faith are blessed with believing Abraham.

The Abrahamic Covenant connects the Ten Commandments of the Old Testament with the Sermon on the Mount in the New Testament, resulting in the new covenant God made with Jesus Himself.  This is important because it clarifies the way God is relating to the human race today – in light of the new covenant and according to who we are in Christ.
