What characteristics you are looking for in god

This is a great question, although it falls into Religious Studies more than English it may just be an English essay or something along the lines of that.

I am someone who doesn't believe in God anymore, I do study Religious Studies and a lot of the religions that believe in God have a lot of similar ideas on what they expect him and his characteristics to be. 

A few key words here that are bound to get you a mark;

God is Omnipotent. 
Having unlimited power.

God is Omniscient.
Knowing everything.

God is Omnibenevolent.
All loving, infinitely good.

If you want in depth definitions of the words I mentioned, you can Google them.

Those are three largely mentioned characteristics of God and I think if you just write them and write paragraphs on each you should get the marks. However, I would like to point out that the question is asking what YOU are looking for in God. That is a question that is completely up to you and your own thoughts. Answer it with your own opinion, and ask yourself what you really look for in God. 

I hope this helped, let me know if you are still stuck with it! ;3
