Why is it important for Christians to know they are sending out God's message?

The role of Christians as messengers of God's Word is integral to the mission of the Church. Just as God assured Zerubbabel of his authority in Haggai 2:20-23, believers today are given the authority of Christ in their proclamation of the Gospel. This empowerment comes from the recognition that they carry the King’s commission and message of reconciliation to a lost world. The Great Commission (Matthew 28:18-20) emphasizes that all authority in heaven and on earth has been given to Christ, and, in turn, He delegates this authority to His followers. Recognizing that they are instruments of God's purpose gives Christians confidence and urgency in their ministry, affirming that despite opposition and personal shortcomings, God is at work through them to accomplish His redemptive plans.
