1 Corinthians 2

v1-5: Faithful pastors have a deep awareness of their own weakness.  "They know how inadequate they are for the great task before them" of preaching Christ and Him crucified.  They are also aware that any fruit from their preaching will only come if the Spirit by "his internal influence on the human heart," brings about faith in those hearing the message.

v6-16: "The great truths of the Gospel are things that lie outside the sphere of human discovery." If these truths "could be discovered by the human eye of reason and communicated by the ear to the mind, as matters of common human knowledge may be" there would be no need for divine revelation.  But we cannot know the gospel unless the Holy Spirit makes it known to us, nor believe it for our salvation unless the Holy Spirit "enlightens the faculty, opens the eye of the heart, and gives us such a knowledge and faith" that we respond by believing in Jesus Christ.
