By order of what makes sense, assuming you are going Box 1 -> Box 4:
Box 1: Romans worshiped many gods.
Box 2: They (the Romans) saw Zealots as radical troublemakers.
Why?
Box 3: They followed the laws and rules of the Torah.
Which states that:
Box 4: God, not the government, was the highest authority.
In this case, the first box sets the reason of this statement. The Romans worshipped many gods, however, they are not above the government, as it is a government instituted religion. They saw the Zealots as radicals, because they followed their own religion, instead of the Roman one. While the Roman one places the Emperor as equal to their gods, and that the government had the greatest authority, the Zealots, instead, placed their faith in their God, which created their natural laws that they follow, instead of the Roman government one.
