Galatians 4:1-5 New King James Version (NKJV)
Sons and Heirs Through Christ
4 Now I say that the heir, as long as he is a child, does not differ at all from a slave, though he is master of all, 2 but is under guardians and stewards until the time appointed by the father. 3 Even so we, when we were children, were in bondage under the elements of the world. 4 But when the fullness of the time had come, God sent forth His Son, born[a] of a woman, born under the law, 5 to redeem those who were under the law, that we might receive the adoption as sons.
Galatians 4:1-5 New International Version (NIV)
4 What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate. 2 The heir is subject to guardians and trustees until the time set by his father. 3 So also, when we were underage, we were in slavery under the elemental spiritual forces[a] of the world. 4 But when the set time had fully come, God sent his Son, born of a woman, born under the law, 5 to redeem those under the law, that we might receive adoption to sonship.[b]
