This means very literally all the laws of Moses (including the 10 commandments) are voided because we find Salvation in Jesus!!!
Your saying "voided" is a slightly different understanding than mine.
I've read that Mosaic Law's 10 Commandments have not been voided, but rather effectively condensed into Jesus' two commandments: Love God and love your neighbor as yourself.
In other words, you can't break any of the Big Ten without also breaking either of Jesus' first or second commandments and, conversely, breaking either of Jesus' two entails breaking one or more of the Mosaic Big Ten.
Jesus is more general with only two. Mosaic law is more specific with the ten.
Regardless, if you have Salvation in Jesus and Him in your heart and live through Him, loving God and your neighbors, you won't be breaking any of the Big Ten anyway, so your way of seeing it is essentially correct to my way of thinking.
Am I close?
Like my British friends like to say: Spot on!
