John Ernst was the eldest son of Frederick of Nassau-Weilburg (1640-1675) and Christiane Elisabeth von Sayn-Wittgenstein (1646-1678). After the death of his parents, his regents were Johann von Nassau-Idstein and after his death, Johann Ludwig von Nassau-Ottweiler. John Ernst became the only ruler of Nassau-Weilburg when his brother Frederick Ludwig was killed in 1684 during the siege of Buda. His territories on the leftbank of the Rhine were occupied by France and only returned after the Treaty of Ryswick in 1697.
John Ernst had an important military career. In 1684 he commanded a Dragoon regiment in the service of the Landgrave of Hessen-Kassel. In 1688, at the start of the Nine Years' War, he defended Koblenz. Later he participated in the Siege of Mainz (1689), the Battle of Fleurus (1690) and the Battle of Landen (1693).
In September 1696 John Ernst entered as general in the service of the Electoral Palatinate als General, which enraged his former employer Charles I, Landgrave of Hesse-Kassel. After the Peace of Ryswick, John Ernst became governor of the Palatinate city of Düsseldorf.
In 1701, at the outbreak of the War of Spanish Succession, John Ernst raised an army, participated in the taking of Landau in 1702 and the consequent chasing of an army under Marshal of France Tallard from the Hunsrück. For this achievement, he was made an Imperial Generalfeldmarschall (General Field Marshal).
When Prince Eugene of Savoy marched in 1703 to Bavaria against the French Marshal Villars, John Ernst stayed on the Rhine to defend Landau against Tallard. This led on November 15 1703 to the Battle of Speyerbach. It was a terrible defeat. 8000 men were lost and John Ernst's eldest son, Colonel Frederick Ludwig of Nassau-Weilburg was killed. Hereafter, John Ernst never fought a major again and withdrew from active service all together in 1706. He was Grosshofmeister of the Elector Palatinate until 1716 and returned to Weilburg, where he died in 1719.
