During the miraculous age, Paul could only say, “For we know in part and we prophesy in part” (1 Corinthians 13:9).
Before the completion of the full revelation of knowledge that we now have as the Bible, each apostle, or other person who had miraculous knowledge or prophecy, could each only say he had part of God’s full revelation, that is, of what He had intended on finally revealing.
However, when He finally revealed everything, there would be no longer a need for miraculous knowledge and prophecy, “But when that which is perfect has come, then that which is in part will be done away” (1 Corinthians 13:10).
“That which is perfect,” is the full revelation of God’s word, so that now each Christian can have in his or her possession, all the knowledge and all the prophecy God desires for us to have.
That being the case, He no longer inspires writers and speakers as He once did, because the job is done.
