There are a lot of things that the Bible says about God. He may be someone who gives a lot of tests to the various characters in the Bible but in the end, He always ends up to be forgiving. The fact that He gave Jesus, His only son to us, in order to save us from our sins already says a lot about the type of God that He is.
He is a creator. He was the one who created the world that we live in right now in 7 days. He has a type of understanding that can be considered incomparable because even if people make mistakes, he is willing to forgive and not be vengeful.
