The authority of God's command is a central theme throughout the Bible, reflecting the divine sovereignty and the ultimate power of God's word. This authority is evident from the very beginning of Scripture, where God's spoken word brings creation into existence. In Genesis 1:3 , "And God said, 'Let there be light,' and there was light." This passage illustrates the immediate and unquestionable power of God's command, as His word alone is sufficient to bring forth reality.

The authority of God's command is further emphasized in the giving of the Law to Moses on Mount Sinai. In Exodus 20, God delivers the Ten Commandments, which serve as a foundational moral code for His people. These commandments are not suggestions but divine imperatives that demand obedience. The authority of these commands is underscored by the context in which they are given, as God speaks directly to Moses amidst thunder, lightning, and the sound of a trumpet, signifying His majesty and power (Exodus 19:16-19).

Throughout the Old Testament, the authority of God's command is also evident in the prophetic tradition. Prophets such as Isaiah, Jeremiah, and Ezekiel are called to deliver God's messages to the people of Israel. These messages often begin with phrases like "Thus says the LORD," indicating that the words spoken by the prophets carry the full weight of divine authority. In Isaiah 55:11 , God declares, "so My word that proceeds from My mouth will not return to Me empty, but it will accomplish what I please, and it will prosper where I send it." This passage highlights the effectiveness and certainty of God's commands.

In the New Testament, the authority of God's command is embodied in the person of Jesus Christ. Jesus speaks with divine authority, as seen in His teachings and miracles. In Matthew 7:28-29 , it is noted, "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." Jesus' authority is further demonstrated in His ability to forgive sins (Mark 2:10) and command the natural elements (Mark 4:39).

The Great Commission in Matthew 28:18-20 is a significant example of the authority of God's command in the New Testament. Jesus, after His resurrection, declares, "All authority in heaven and on earth has been given to Me. Therefore go and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, and teaching them to obey all that I have commanded you." This command carries the full weight of divine authority, as it is issued by the risen Christ, who possesses all authority.

The authority of God's command is also evident in the writings of the apostles. In 2 Timothy 3:16 , Paul affirms the divine inspiration and authority of Scripture: "All Scripture is God-breathed and is useful for instruction, for conviction, for correction, and for training in righteousness." This passage underscores the belief that the Bible, as the written word of God, carries His authority and is the ultimate standard for faith and practice.

In summary, the authority of God's command is a pervasive theme in the Bible, manifesting in creation, the Law, the prophets, the teachings of Jesus, and the apostolic writings. This authority demands obedience and reverence, as it originates from the sovereign Creator and Sustainer of all things.
