Throughout his ministry, Peter faithfully watched over the flock entrusted to his care, and thus proved himself worthy of the charge and responsibility given him by the Saviour. Ever he exalted Jesus of Nazareth as the Hope of Israel, the Saviour of mankind. He brought his own life under the discipline of the Master Worker. By every means within his power he sought to educate the believers for active service. His godly example and untiring activity 517 inspired many young men of promise to give themselves wholly to the work of the ministry. As time went on, the apostle's influence as an educator and leader increased; and while he never lost his burden to labor especially for the Jews, yet he bore his testimony in many lands and strengthened the faith of multitudes in the gospel.

Under hele sin virksomhed vogtede Peter med troskab den hjord, der var betroet til hans omsorg og viste sig således værdig til det kald og det ansvar, Frelseren havde givet ham. Altid priste han Jesus fra Nazaret som Israels håb, menneskehedens Frelser. Han gav sit eget liv ind under den øverste arbejders tugt. Ved alle midler, der stod i hans magt, søgte han at opdrage de troende til aktiv tjeneste. Hans fromhed og utrættelige flid tilskyndede mange lovende unge mænd til helt at give sig over til arbejdet i tjenesten. Efter som tiden gik, blev apostlens indflydelse som opdrager og leder større og skønt han aldrig frigjorde sig for den opgave i særlig grad at arbejde for jøderne, vidnede han i mange lande og styrkede troen på evangeliet hos mange.
