Galatians 4:1-11

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]; 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]. 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]. [Rom 11:17-24] And because you [really] are [His] sons, God has sent the Spirit of His Son into our hearts, crying out, “Abba! Father!” Therefore you are no longer a slave (bond-servant), but a son; and if a son, then also an heir through [the gracious act of] God [through Christ]. But at that time, when you did not know [the true] God and were unacquainted with Him, you [Gentiles] were slaves to those [pagan] things which by [their very] nature were not and could not be gods at all. Now, however, since you have come to know [the true] God [through personal experience], or rather to be known by God, how is it that you are turning back again to the weak and worthless elemental principles [of religions and philosophies], to which you want to be enslaved all over again? [For example,] you observe [particular] days and months and seasons and years. I fear for you, that perhaps I have labored [to the point of exhaustion] over you in vain.
