Ether, as the Lord’s chosen prophet, was untiring in his ministry in exhorting his people to repent in order to avert destruction. He was so filled with the Spirit of the Lord that he could not be restrained by others or prevented by them from fulfilling his divine mandate (compare Mosiah 13:2-7). Being filled with the Spirit also compelled Ether, as it can work upon us, to magnify his calling and not be distracted or diverted from such important work by things of lesser significance.
