'Subject' in the Bible

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.

But when [in God’s plan] the proper time had fully come, God sent His Son, born of a woman, born under the [regulations of the] Law,

so that He might redeem and liberate those who were under the Law, that we [who believe] might be adopted as sons [as God’s children with all rights as fully grown members of a family].

But if you are guided and led by the Spirit, you are not subject to the Law.
