He was a fearless reprover of sin. While he preached the love of God in Christ to the people of his time, and pleaded with them to forsake their evil ways, he rebuked the prevailing iniquity and warned the men of his generation that judgment would surely be visited upon the transgressor. It was the Spirit of Christ that spoke through Enoch; that Spirit is manifested, not alone in utterances of love, compassion, and entreaty; it is not smooth things only that are spoken by holy men. God puts into the heart and lips of His messengers truths to utter that are keen and cutting as a two-edged sword.

Han var en frygtløs revser af synd. Mens han forkyndte Guds kærlighed gennem Kristus for folket på sin tid og opfordrede dem til at forlade deres onde veje, irettesatte han den herskende ugudelighed og advarede sin tids mennesker om, at dommen ganske bestemt ville blive fuldbyrdet over overtræderen. Det var Kristi ånd, der talte gennem Enok. Denne ånd åbenbarer sig ikke alene ved kærlighed, medfølelse og bøn; det er ikke udelukkende milde ord, der tales af hellige mænd. Gud pålægger sine budbærere at forkynde sandheder, som er skarpe og gennemtrængende som et tveægget sværd.
