Sonship in Christ

4 Now what I mean [when I talk about children and their guardians] is this: as long as the heir is a child, he does not differ at all from a slave even though he is the [future owner and] master of all [the estate]; ² but he is under [the authority of] guardians and household administrators or managers until the date set by his father [when he is of legal age]. ³ So also we [whether Jews or Gentiles], when we were children (spiritually immature), were kept like slaves under the elementary [man-made religious or philosophical] teachings of the world.
