The Bible rings with the theme of family all throughout its pages. God has a pattern of operating with and working through families. The Bible presents a picture of two types of families; those who belong to Him, and those who are part of the world. To use terms from Genesis 3:15, people are either called the children of the woman or the children of the serpent. There is no third category.
From now on, you and the woman will be enemies, and your offspring and her offspring will be enemies. .... Genesis 3:15 (NLT)
Using the categories mentioned above, who are those who belong to God? Are they just adults? Are those who are “children of the woman” just those who are old enough to profess faith in God? Of course not. His people have always included parents (adults) together with their children. His people have always included singles, babies, and grandparents. God’s family always referred to those who were part of the nation of Israel or who are now part of the church.
So now you Gentiles are no longer strangers and foreigners. You are citizens along with all of God's holy people. You are members of God's family. Ephesians. 2:19 (NLT)
This family theme has never changed since the dawn of history. But, what does it mean? Well, let's take a look. We’ll see in this brief study that God’s blessing is given to adults who believe, together with their children. This is the way God has always acted - parents together with their children, either in blessing or in judgment. Let's look at the way this pattern works itself out in biblical history.
