Here is the rest of the "who is God" list:
God is Holy and Righteous ~ 1 John 1:5
God is Love ~ Romans 5:8
God is Faithful ~ Hebrews 10:23
God is Unchangeable ~ Malachi 3:6
If you are interested in learning more about who God is and what he is like, I would recommend reading On Who is God: A Book You'll Actually Read by Mark Driscoll. It's very short, but really packed with information. There are several books in this series, but this is the only one I have read. If you read it, let me know what you think.
