Don't even try! It's terrible English. It's obviously been translated from another language by a person who doesn't know English very well.

I'm not sure which translation this is from but it is difficult. You will probably need to look at the surrounding verses for context and meaning. Try this website for other versions of the same verse. http://biblehub.com/romans/11-33.htm Did you mean you can't understand? It basically means that God's judgements and ways are so deep that we may have trouble understanding them. Beyond that it would be interpretation based on the reader's theological beliefs.
