What is God's 'true nature'?

Most Christians say and think that God's true nature is love, as Jesus said in the book of John 3:16. Is this correct or not? I would like to understand what God's true nature is before I read the Bible. I think I can understand the Bible better if I clearly know his true nature is. 

John 3:16

ESV - ¹⁶ For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
