Galatians 4:1-3 NIV

1 What I am saying is that as long as the heir is a child, he is no different from a slave, although he owns the whole estate.
2 He is subject to guardians and trustees until the time set by his father.
3 So also, when we were children, we were in slavery1 under the basic principles of the world.2
