Family is important to God, and it is clear that He does not think merely in terms of individuals but also in terms of generations. Matthew 1:17 tells us: “So all the generations from Abraham to David are fourteen generations, from David until the captivity in Babylon are fourteen generations, and from the captivity in Babylon until the Christ are fourteen generations.”
When God looks at you, He also sees your family. He sees where you came from. He looks at your ancestors, and He looks at your children and grandchildren.
When making a covenant with Abraham, God never once said, “I’m going to bless you.” He always said, “I am going to bless you and your descendants.” An example of this is in Genesis 22:17-18, where God said, “In blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies. In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.”
Abraham obeyed God and was blessed, and his descendants were blessed, too, because blessings tend to run along blood lines.
