It stands to reason that if I believe verse 17 is about the Old Law, then verse 16 is talking about the Old Law and not the New Law, too. Oh, and I am not going beyond what is written. Galatians gives us many clues it is referring to the law of Moses and not all law whatsoever. For starters, Galatians 2:3 says this:
"But neither Titus, who was with me, being a Greek, was compelled to be circumcised:"
Is circumcision a part of the New Law or the Old Law? But what about the moral law in the Old? Does that mean we are not under the moral law of the Old? No. Because the moral law has been repeated in the New and the moral law in the New does not have death penalties attached to some of them. We are under a completely different Covenant with new laws or commands. In fact, we know that the moral law is still in effect because Paul says in Galatians 5:19-24,
"Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law. And they that are Christ's have crucified the flesh with the affections and lusts."
Notice verse 23? It says if one has the fruits of the Spirit then there is no law against that.
For verse 18 says,
"But if ye be led of the Spirit, ye are not under the law."
We see two contrasts here.
#1. Works of the flesh (by which one will not inherit the Kingdom of God).
#2. Fruits of the Spirit by which one would not be under the Law (if they have them).
There is no third category of a believer getting away with one or two sins on occasion with the thinking they are saved. One either has the fruits of the Spirit or the works of the flesh; And the list of sins to breaking certain moral laws in Galatians 5 lets us know that the moral law has not been abrogated in regards to salvation. For be not deceived. The unrighteous shall not inherit the Kingdom of God.
