The key to Enos' experience is the hunger in his soul. Enos does not have his transformational experience because he thought it might be nice to have one. His struggle before the Lord (verse 1) was a real effort, not a tossed-off prayer. Enos speaks of a real desire from the core of his spiritual being. He accurately represents it as a struggle for he was required to fight through his natural man to his spiritual self. His hunger for the spirit was greater than his hunger for food, for he indicates that he prays throughout a day and a night.
We do not really know with what topics Enos occupied his prayer for that length of time, but we may assume from his subsequent statements that it became a time of self-revelation and realization of his standing before God. It certainly became a time of sincere repentance of acting upon the self-revelations he uncovered.
