Adjectival form of Mesopotamia. Pertaining to the region between the Tigris and Euphrates rivers. Describes people or things from this ancient cradle of civilization.
The adjective connects to the narrative of God's sovereign work across geographic and cultural boundaries. That the gospel reached people from Mesopotamia at Pentecost (Acts 2:9) fulfills God's promise to Abraham that all nations would be blessed through his seed — including the very land from which Abraham had been called out.
