53:4 As the number of believers multiplied in Jerusalem and in other places visited by the messengers of the cross, the talents possessed by Peter proved of untold value to the early Christian church. The influence of his testimony concerning Jesus of Nazareth extended far and wide. Upon him had been laid a double responsibility. He bore positive witness concerning the Messiah before unbelievers, laboring earnestly for their conversion; and at the same time he did a special work for believers, strengthening them in the faith of Christ.
