Lincoln states that secession had not legally dissolved the United States. Because he regarded the Union as constitutionally continuous, he treated the seceding states as remaining within the country and subject to federal law. Their declarations of secession therefore did not, in his view, remove them from the authority of the national government.

He links this position to the president’s constitutional duty to ensure that federal laws are faithfully executed. The passage presents enforcement not simply as a political choice, but as an obligation attached to public office. It also establishes the legal basis for maintaining federal property, collecting duties and continuing government operations.

At the same time, Lincoln elsewhere in the address stressed restraint and denied any intention to interfere unnecessarily with local institutions. The statement therefore combines a firm rejection of secession with a claim that executive action would remain bounded by constitutional authority.
