3 Attributes of God that remind us that He is not like us:
1. God is Eternal - God has no beginning and no end. He does not live in successive moments of time, but instead sees all time equally vividly, yet God sees in time and acts in time. God is transcendent in that He is bigger than time and space. No one has given him life, and no one can take away that life. God has life in himself. Before the world was made, God needed nothing to make him happy or to make him God, he is self-existent and self-sufficient. God has it all, without beginning and without ending. (Psalm 90:1-2)
2. God is Holy - The Bible speaks of a lot of God's holiness. To be holy means to be different from all else - to be unique or separate or set apart. An important element of God's holiness is that He is completely separate from all that is wrong or impure or sinful. He has life that cannot be stained by anything bad. Because God is truth He cannot lie or believe a lie. Because God is faithful He cannot go back on His word or break a promise. Because God is righteous, He cannot do what is evil or consider the evil that others do as okay or acceptable. He is holy, and so he is separated from anything that is contrary to his own life as God. (Isaiah 6:3; Exodus 15:11)
3. God is Unchangeable - God is God, and this means He cannot be less than who He is as God, just as He cannot be other than who He is as God. God has every quality within his own life as God, and because of this, He simply cannot change for the better or for the worse. God is the same today as He was yesterday or 5,000 years ago. God is who He ever is, and nothing in the very character of God can change. He can be relied on, trusted, and followed, for He does not sway like the trees with every passing wind. (Psalm 102:25-27)
Considering that God is eternal, holy, and unchangeable should bring us to both praise for God's greatness and trust because of the faithfulness of His character. We can count on Him. He has all power, wisdom, and goodness. Knowing these things lead us to honor Him, worship Him, trust Him, and humble ourselves before Him. He is not like us.
