4 But when the fulfillment of the time came, God sent his Son, born through a woman, and born under the Law.
5 This was so he could redeem those under the Law so that we could be adopted.
6 Because you are sons and daughters, God sent the Spirit of his Son into our hearts, crying, "Abba, Father!"
7 Therefore, you are no longer a slave but a son or daughter, and if you are his child, then you are also an heir through God.
8 At the time, when you didn’t know God, you were enslaved by things that aren’t gods by nature.
9 But now, after knowing God (or rather, being known by God), how can you turn back again to the weak and worthless world system? Do you want to be slaves to it again?
10 You observe religious days and months and seasons and years.
