If we believe that Jesus Christ is the Son of God, and only if, then the only accurate description we have of God is given to us in the words of Jesus Christ. Even then we can't take it as gospel as we can only make (informed) guesses as to which words came out the mouth of Jesus and which ones were purely the invention of the writers of the gospels.
We can have our own ideas about the nature of God above and beyond the claims of Jesus and we can choose to believe what other people believe. But we cannot claim that they are true. Therefore we should never insist that other Christians believe these unverified characteristics of God. We certainly should never force non-believers into living their lives in accordance with our guesses about the nature of God.
