I think also as the Declaration of Independence says "Prudence, indeed, will dictate that Government long established should not be changed for light or transient causes..." Prudence, in other words, dictates first going for state court and legislative nullification of abhorrent federal laws, using every means possible before deciding on cessation as the final answer.
Personally, I believe that at some point cessation of those that hate tyranny and love freedom appears inevitable. But I also believe in going through all the steps necessary to avoid it if at all possible.
Specifically, it’s from:
“The Unanimous
Declaration of Independence
made by the
Delegates of the People of Texas
in General Convention
at the town of Washington
on the 2nd day of March 1836.”

Written literally overnight in bitter cold at Washington-on-the-Brazos.
Our state Constitution goes one step further:
All political power is inherent in the people, and all free governments are founded on their authority, and instituted for their benefit. The faith of the people of Texas stands pledged to the preservation of a republican form of government, and, subject to this limitation only, they have at all times the inalienable right to alter, reform or abolish their government in such manner as they may think expedient.
Article 1, Section 2, Texas State Constitution.
I think you mean secession. As in, "the Southern states seceded from the Union."
