Definition and Concept:
Great authority in the biblical context refers to the power, dominion, and influence that is granted or inherent to individuals, institutions, or spiritual beings. This authority is often seen as divinely ordained and is exercised in various realms, including spiritual, political, and social spheres. The concept of authority is deeply rooted in the sovereignty of God, who is the ultimate source of all authority.

Biblical Instances:

1. Divine Authority:
· God is depicted as the supreme authority over all creation. His authority is absolute and unchallenged. In the book of Daniel, it is stated, "He changes times and seasons; He removes kings and establishes them. He gives wisdom to the wise and knowledge to the discerning" (Daniel 2:21). This verse underscores God's sovereign control over earthly rulers and events.

2. Jesus Christ:
· Jesus is portrayed as possessing great authority, both in His teachings and His miraculous works. In the Gospel of Matthew, it is recorded, "When Jesus had finished saying these things, the crowds were astonished at His teaching, because He taught as one who had authority, and not as their scribes" (Matthew 7:28-29). His authority is further emphasized in the Great Commission: "All authority in heaven and on earth has been given to Me" (Matthew 28:18).

3. Apostolic Authority:
· The apostles were granted authority by Christ to preach the Gospel, perform miracles, and establish the early Church. In the book of Acts, Peter and John are described as speaking with boldness and authority, leading to the growth of the Church (Acts 4:13).

4. Earthly Rulers:
· The Bible acknowledges the authority of earthly rulers as instituted by God. Romans 13:1 states, "Everyone must submit himself to the governing authorities, for there is no authority except that which is from God. The authorities that exist have been appointed by God." This passage highlights the divine sanction of governmental authority.

5. Spiritual Authority:
· Believers are endowed with spiritual authority to resist evil and advance God's kingdom. In Ephesians 6:10-12 , Paul exhorts Christians to "put on the full armor of God" to stand against spiritual forces of evil, indicating the authority believers have in spiritual warfare.

Theological Implications:

· Sovereignty of God: The concept of great authority underscores the sovereignty of God over all aspects of life. It affirms that all authority is derived from Him and is subject to His will and purpose.

· Responsibility and Stewardship: Those who are granted authority are called to exercise it responsibly and justly, reflecting God's character. Authority is not for self-aggrandizement but for service and the common good.

· Submission and Obedience: Believers are called to submit to legitimate authority as an act of obedience to God, recognizing His ultimate authority over all human institutions.

· Empowerment of Believers: The authority given to believers through Christ empowers them to live victoriously, proclaim the Gospel, and engage in spiritual warfare.

Conclusion:
The biblical concept of great authority is multifaceted, encompassing divine, Christological, apostolic, governmental, and spiritual dimensions. It is a testament to the order and purpose God has established in creation, calling for responsible stewardship and faithful obedience.
