In 60 a.d., an aging prisoner bows his knees upon the stone floor of a rented house in Rome. A forged iron chain rubs against his wrist with every shift of his weight. He dictates words to a companion while an imperial soldier stands chained to his arm. The man ignores the physical strain and maps out the dimensions of a divine inheritance.
The captive is Paul of Tarsus. He dictates this letter from imperial Rome during the early seventh decade of the first century. His audience lives across the Aegean Sea in the merchant city of Ephesus. Roman magistrates hold him under armed guard for disturbing the peace of the empire. He writes to stop these Gentile converts from losing heart over his imprisonment. For centuries, limestone warning tablets in Jerusalem threatened death to any foreigner crossing into the inner sacred courts. Paul declares that the Architect demolished that dividing wall. His captivity serves as the physical price of bringing outsiders into the commonwealth. He explains this divine plan as a master surveyor revealing a new property line. The Gentile believers stand as equal heirs to the promise of Christ.
A surveyor stretches a braided flax line across open ground to lock four true corners before laborers drop heavy foundation stones into the dirt. Without that tight string to guide the masons, rising stone walls drift out of square and buckle under their own weight. Paul applies this strict site measurement to the love of Christ. He commands his readers to calculate its breadth, length, height, and depth. Men abandon what they cannot measure or comprehend when suffering arrives. By forcing the mind to gauge the vast dimensions of this spiritual foundation, the apostle anchors their endurance against the panic of persecution. The iron chain on his arm acts as temporary scaffolding. The measured stone beneath their feet remains permanent.
Never trust a rising wall masons build without a taut plumb line. Heavy timber and rough storms always expose a crooked foundation.
Roman legions reduced the limestone dividing walls of Jerusalem to rubble in 70 a.d. and left no physical barrier between tribes. The dictated letter survived the collapse of both the imperial throne and the marble temples of Ephesus. The document preserves the measured foundation of a worldwide faith.
