Galatians 4:6-10

6And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, “Abba, Father!”

7Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ.

8But then, indeed, when you did not know God, you served those which by nature are not gods.

9But now after you have known God, or rather are known by God, how is it that you turn again to the weak and beggarly elements, to which you desire again to be in bondage?

10You observe days and months and seasons and years.
