"How do you interpret that verse?"
The verse is already interpreted, but if you mean, "how do you apply that verse/how do you understand that verse?", I would say this- you will either perish under the Law, or apart from the Law, unless you are saved by grace. At that point you are freed from needing to keep the Law as a requirement for entrance into Heaven and eternal life.
I only skim what you have to say. You are a fool, in the total biblical sense, and you are not interested in anything apart from being a imgflip Troll™. But your points are laughable, to say the least, and yet it breaks my heart to see someone so full of themselves despite being a small speck on a small planet in a relatively small galaxy.
"And it's not like God himself is coming down and proving anything."
As I said previously, you follow the script of the godless to a tee. Claiming to be an atheist, you believe this is all nothing, and yet you work so hard to make yourself believe this.
2 Peter 3:3-4
Knowing this first of all, that scoffers will come in the last days with scoffing, following their own sinful desires.
They will say, “Where is the promise of His coming? For ever since the fathers fell asleep, all things are continuing as they were from the beginning of creation.”
