Definition and Nature:
Divine power and authority refer to the supreme and sovereign ability and right of God to govern all creation. This concept is foundational in Christian theology, emphasizing God's omnipotence, omniscience, and omnipresence. Divine power is the inherent strength and capability of God to accomplish His will, while divine authority is the legitimate right to command, rule, and judge.

Biblical Foundations:
The Bible consistently affirms God's ultimate power and authority over the universe. In Genesis 1:1, the creation account begins with God's authoritative command, "In the beginning, God created the heavens and the earth." This act of creation is a demonstration of His power and authority over all things.

In the New Testament, Jesus Christ is depicted as possessing divine power and authority. In Matthew 28:18, Jesus declares, "All authority in heaven and on earth has been given to Me." This statement underscores His divine authority, which is derived from His unity with the Father.

Manifestations of Divine Power:
1. Creation: God's power is evident in the creation of the world. Psalm 33:6 states, "By the word of the LORD the heavens were made, and all the stars by the breath of His mouth." This creative act is a testament to His unmatched power.

2. Sustenance: God not only created the universe but also sustains it. Hebrews 1:3 describes Jesus as "sustaining all things by His powerful word." This ongoing sustenance is a continuous exercise of divine power.

3. Miracles: Throughout the Bible, miracles serve as manifestations of divine power. In the Gospels, Jesus performs numerous miracles, such as calming the storm (Mark 4:39) and raising Lazarus from the dead (John 11:43-44), demonstrating His authority over nature and life.

4. Salvation: Divine power is also evident in the work of salvation. Romans 1:16 refers to the gospel as "the power of God for salvation to everyone who believes." This power transforms lives and redeems humanity from sin.

Divine Authority in Governance:
God's authority is not limited to creation and miracles but extends to His governance of the world. Proverbs 21:1 states, "The king’s heart is a waterway in the hand of the LORD; He directs it where He pleases." This illustrates God's sovereign control over human affairs.

Jesus Christ and Divine Authority:
Jesus Christ, as the Son of God, embodies divine authority. His teachings, miracles, and resurrection affirm His authority. In John 10:18, Jesus speaks of His authority over life and death: "No one takes it from Me, but I lay it down of My own accord. I have authority to lay it down and authority to take it up again."

The Role of the Holy Spirit:
The Holy Spirit also exercises divine power and authority. Acts 1:8 promises believers, "But you will receive power when the Holy Spirit comes upon you." The Spirit empowers believers to live according to God's will and to spread the gospel.

Human Response to Divine Authority:
Believers are called to recognize and submit to God's authority. James 4:7 instructs, "Submit yourselves, then, to God. Resist the devil, and he will flee from you." Submission to divine authority is an act of faith and obedience.

Eschatological Authority:
In the end times, God's authority will be fully realized. Revelation 11:15 proclaims, "The kingdom of the world has become the kingdom of our Lord and of His Christ, and He will reign forever and ever." This future reign underscores the ultimate triumph of divine authority.

Conclusion:
Divine power and authority are central to understanding God's nature and His relationship with creation. Through His power, God creates, sustains, and redeems, while His authority governs and directs all things according to His perfect will.
