Galatians 4:8

5 that those under law he may redeem, that the adoption of sons we may receive;

6 and because ye are sons, God did send forth the spirit of His Son into your hearts, crying, `Abba, Father!`

7 so that thou art no more a servant, but a son, and if a son, also an heir of God through Christ.

8 But then, indeed, not having known God, ye were in servitude to those not by nature gods,

9 and now, having known God -- and rather being known by God -- how turn ye again unto the weak and poor elements to which anew ye desire to be in servitude?

10 days ye observe, and months, and times, and years!

11 I am afraid of you, lest in vain I did labour toward you.
