This morning I preached from the short statement by the Apostle Paul, "For what we know is incomplete and what we prophesy is incomplete." (1Co 13.9)
This is quite a statement; an apostle, one who has seen the risen Lord, admits that his knowledge (and his prophesying) is incomplete...there are gaps in knowledge and in prophecy. John Wesley comments on this admission in his Explanatory Notes:
"For we know in part, and we prophesy in part - The wisest of men have here but short, narrow, imperfect conceptions, even of the things round about them, and much more of the deep things of God. And even the prophecies which men deliver from God are far from taking in the whole of future events, or of that wisdom and knowledge of God which is treasured up in the scripture revelation."
In other words, we're ignorant; I mean that in a good way! :-) we are incomplete in our information concerning things spiritual.
Now, I'm not saying we have an incomplete knowledge of the necessities--I completely believe God's Word from Genesis to Revelation is complete for our lives on this earth. The Spirit reveals Christ in the Word, and Christ glorifies God. However, the Bible doesn't contain all of the mind of God (which is impossible) or all the things that could be known (which is unnecessary). God revealed what he wished to reveal and that is limited; it leaves us in ignorance, and that's just fine because God wanted it that way!
