JMNT(i)
7 So that, you are (you exist being) no longer a slave, but rather, a son, and since a son, also an heir (a possessor and an enjoyer of the distributed allotment) through God [other MSS: God's heir through Christ].
8 But on the other hand, at that time, in fact, having not perceived and thus not knowing God, you folks were, and performed as, slaves to (or: for) those [who], by nature, are not gods.
9 Yet now, coming to know God by intimate experience and personal insight – or, rather, being known intimately by God – how are you folks progressively turning around again, upon the weak (feeble; infirm; diseased; impotent) and poor (beggarly) elementary and rudimentary principles to which (for which; in which) you people are presently wanting (and progressively intending) to again become, and perform as, slaves anew (or: back again)?
10 You are for yourselves and in yourselves continuously watching closely and observing days [e.g., sabbaths; days for fasting] and months (or: new moons) and seasons (or: appointed situations [e.g., feasts]) and [sacred] years!
