God is not the same as the world.The meaning of the verse, "You were shown to known that the Lord is God, there is none other besides Him," means there are no other gods besides Him.

In Torah, God is not thought to be the same as the world. I do not know from where people get the opposite idea from. The meaning of the verse, "You were shown to known that the Lord is God, there is none other besides Him,"  means there are no other gods besides Him. But on a deeper level it means that  everything besides God can not exist without Him. This is clear in all Rishonim when they discuss the basic core beliefs of Torah. You can see this in all Musar books of the Rishonim. In the first seven laws of Mishna Torah you can see this also. There the Rambam explains "there is none besides Him" to mean the existence of everything besides God is dependent on God. 

None of that implies that God is the same as the world.
