Genesis 4:26

And to Seth, to him also there was born a son; and he called his name Enos. Then began men to call upon the name of the Lord. The family of Seth was the family of believers, and it was during the lifetime of his son Enos that men began formally to proclaim the name of Jehovah, to institute public services for the purpose of worshiping Him in prayer, praise, and the giving of thanks. So the name of the Man, Jehovah, in whom Eve had trusted, was now preached openly; the coming of the Messiah was openly declared. Thus today, in the midst of a world steeped in sin, the glorious Gospel of the Savior is proclaimed, and we have comfort in the assurance of our salvation through His power.
