Creation

God created everything. All things seen and unseen, from the smallest particles to the largest galaxies, everything that is was made by God. Genesis 1-2, Colossians 1:16, Hebrews 1, Revelation 4:11

He brought everything into existence out of nothing simply by speaking. By His command, all reality was formed, shaped, and given purpose. He was and is and will continue to be intimately involved in every aspect of creation from the most distant reaches of the universe to the daily course of life.
Genesis 1:1-3, Job 36-41, Psalm 139

God created everything to provide a witness of His existence. Creation tells us something about who God is and what He is like. Ultimately, everything exists to declare the majesty, beauty, perfection, and glory of God. Creation originally operated with harmony, order, and purpose. God also created people uniquely to bear His image as a testimony to His glory and goodness. God charged His people with the privilege of sharing in His rule and care for the world by filling it with offspring. God provided everything needed for them to fulfill their purpose of organizing the world into a sanctuary of intimate fellowship with God.
Genesis 1:26-28, Psalm 19, Acts 14:17, 17:26-28, Romans 1:19-20, 1 Corinthians 10:31

God has authority over what He has made. This authority extends to everything, including every person who has ever lived. Everyone will give an account to God for the life they were given and how they used their words, deeds, thoughts, motivations, and desires to bring glory to Him.
Psalm 29, Matthew 12:33-37, Romans 2, 3:19, Revelation 20:11-15
