6 Therefore, because you are sons, God has sent the Spirit of his Son into your hearts, crying out: "Abba, Father."
7 And so now he is not a servant, but a son. But if he is a son, then he is also an heir, through God.
8 But then, certainly, while ignorant of God, you served those who, by nature, are not gods.
9 But now, since you have known God, or rather, since you have been known by God: how can you turn away again, to weak and destitute influences, which you desire to serve anew?
10 You serve the days, and months, and times, and years.
11 I am afraid for you, lest perhaps I may have labored in vain among you.
12 Brothers, I beg you. Be as I am. For I, too, am like you. You have not injured me at all.
