He was born in Frederikshald as a son of major Georg Frederik Rode and his first wife Vilhelmine, née Stockfleth.
He was promoted to premier lieutenant in 1790 and captain in 1800, and in the same year he became aide-de-camp for the governor in Rendsborg, Prince Frederick of Hesse.
When the former Crown Prince Christian Frederick of Denmark was elected King of Norway by the Norwegian Constituent Assembly in May 1814, Rode was appointed chamberlain with the rank of colonel in the same month.
During the Swedish campaign against Norway of the summer, which would eventually oust Christian Frederick, Rode commanded a brigade—which did not see military action.
Having become general commissary of war in October 1814, he remained so until his death at the farm Søndre Hellerud in December 1830.
