To fulfill the Word of God means to carry out God's divine will and purpose as revealed through Scripture.
In the context of Colossians 1:25, fulfilling the Word of God involves the faithful proclamation and teaching of the Gospel as ordained by God. It indicates a minister's duty to declare the whole counsel of God, encompassing both the grace and the requirements of the faith. Paul exemplifies this by not holding back any part of the message, as seen in Acts 20:27. This fulfillment is carried out by relying on the Holy Spirit's empowerment, ensuring that the message of salvation found in Christ is comprehensively communicated. Therefore, every faithful minister strives to correctly handle and deliver the Word of God to build up the church and spread the Gospel.
