God is sovereign, so we are all under His law and are obligated to refrain from doing what He has revealed to be sin regardless of whether or not we seek to be under it. I would think that anyone who affirmed that the Torah is accurately described in Psalm 19:7-11 would jump at the opportunity to get to experience being a doer of it regardless of whether or not they are unThder it.
The only way to attain a character trait is through faith apart from being required to have first done enough works in order to earn it as the result, but what it means to have a character trait is to be a doer of works that embody that trait. For example, the only way for someone to become courageous is through faith apart from being required to have first done enough courageous works in order to earn it as the result, but it would be contradictory for someone to become courageous apart from becoming a doer of courageous works, and the same is true for righteousness (1 John 3:4-7, Isaiah 51:7), and every other character trait.
The Torah was never given as a way of earning our righteousness even as the result of having perfect obedience (Romans 4:1-5), but rather it was given to describe the works that a righteous person is a doer of as it describes the works of Christ, so it is what we get to experience by being given the gift of righteousness through faith. Paul also affirmed in Romans 2:13 that only the doers of the Torah will be declared righteous, so there is a reason why our righteousness requires us to choose to be a doer of the Torah other than in order to earn it as a result, namely faith insofar as the faith by which we are declared righteous apart from works also upholds the Torah (Romans 3:28-31).
The Hebrew word “yada” refers to intimate relationships/knowledge gained by experience, such as with Genesis 4:1 where Adam knew (yada) Eve, she conceived, and gave birth to Cain. God’s way is the way to know (yada) Him and Jesus by having the experience of embodying His character traits, which is the narrow way to eternal life (John 17:3). For example, in Genesis 18:19, God knew (yada) Abraham that he would teach his children and those of His household to walk in His way by being doers of righteousness and justice that the Lord might bring to him all that He has promised. In Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know (yada) Him, and in Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so the goal of the Torah is to graciously teach us how to experience an intimate relationship with God and Jesus by walking in His way, which is His gift of eternal life.
