Behold, I went to hunt beasts in the forests; and the words which I had often heard my father speak concerning eternal life, and the joy of the saints, sunk deep into my heart.
And my soul hungered
Something about the teachings of Enos's father (Jacob) sunk deep into his heart. We often hear people say that the word of God has a "more powerful effect upon the minds of the people than the sword, or anything else." When I hear this I often assume that it refers to doctrine, that true doctrine changes minds. But in fact this verse teaches that preaching "the joy of the saints" changes minds too.
The question is, how do we preach "the joy of the saints" with words (Jacob taught this with words)? In my mind joy is something seen not spoken. But perhaps I need to do a better job articulating the joy I find in Christ.
