He studied theology at Utrecht, and from 1832 to 1837 served as a pastor in Stiens. Afterwards he taught classes at the Rijksatheneum in Franeker, and in 1840 relocated to the University of Groningen, where he was a professor of theology.
Muurling was a prominent member of the so-called "Groningen School", which was a progressive movement within the Dutch Reformed Church.
