Writing is a unique gift from God. Although it is not specifically mentioned as a definite gift, it can easily facilitate all of the listed gifts of the Spirit in a very special and personal way. God's inspired word, the Bible, was given to us through the operation of the Holy Spirit, using the written word and the personalities of many authors over centuries.
There is a permanency to the written word which seems to defy time. Once a thought is put on paper, it is there for the world to see and digest for generations. Just as the Holy Spirit gave us revelation through the Bible, so also the Holy Spirit can illuminate the truths in God's word to our hearts. Through writing, we can share the nuggets God has opened up to us and bless the body of Christ.
In my own life, I have felt the calling to minister to Christ's body through writing. Many times thoughts and lesson outlines will "hit me" in some unusual places, and I realize these insights are meant to be shared with others. I am constantly challenged to be a faithful and obedient writer in whatever avenues become available. May His name ever be glorified through this precious gift.
