Galatians 4:1-2
Paul explains what it means to be God's children
1 I will explain it like this. Think about a son who will one day receive what belongs to his father. While he is still a child, he is no better than a slave in the family. This is true, even though all his father's things belong to him. 2 He has to wait until the time that his father has decided. Until then, the son has to obey his teachers and the guides who take care of him.
