My writing is a ministry, because ministry is service, and every aspect of our lives is to be a service that glorifies our Lord:
“Whether you eat or drink or whatever you do, do it all for the glory of God” (1 Cor. 10:31).
“And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him. (Col 3:17)
“Whatever you do, work at it with all your heart, as working for the Lord, not for men...It is the Lord Christ you are serving” (Col. 3:23-24).
Is writing included in the “whatever” I do? Yes. And therefore, I do it with all my heart, to the glory of God, as a service to the Lord first and to others second, aware that I must seek to please the Audience of One, whose judgment seat is the only one I'll stand before, and whose opinion of my life is the only one that matters. I do this service giving thanks to God for the privilege of being his errand boy, his messenger, his servant. By viewing writing as a ministry first and a vocation only second, I remind myself it's not about me, it's about Him.
