Paul says that because of this need, he had become the diakonos or minister (one who executes the commands of another, a servant), to the church through the stewardship (Greek oikonomía) or one who manages a household or household affairs from God Himself with the express commission to preach the Word completely. The Greek word uses for fully is pleroo means completely or to bring to realization. The word of God achieves it purpose when it is freely proclaimed in the world and is accepted in faith.
Paul’s special responsibility in fully proclaiming the word of God was his special apostleship to the Gentiles, of course, this included these Colossian believers. We see a parallel to this concept in Ephesians 3:8. Paul’s purpose was the purpose God had set for him, and so Paul’s message was pure and uncorrupted by the false teaching in his day.
Prayer: Heavenly Father, may I be entrusted with the service of declaring Your Word to those You place in my path. May I speak Your words, and may I be faithful to fulfill the opportunities You give me as Your servant. I want to be an oikonomia for Your Son, my Lord Jesus Christ. Amen.
