Is there more than one way to God?

I have been a protestant christian my entire life. Now I am at a point in my life that I question everything i believe. I am well versed in scripture and understand the origins of Christianity, Judaism and Islam. I've made enough mistakes in my life that I wish I had a "re-do", which has me wanting to know more about buddhism. Could God be so close-minded that there can be only one way to Him? I am at a crossroad trying to determine whether to continue with Christianity or seek other ways. Can you practice the teachings of Buddhism WITH Christianity? My bible says "thou shall have no other gods BEFORE me." It doesn't say not to at all.....
