Isaiah 40

I spent about 6 minutes reading this chapter. Why is it that some people reject God? I suppose some don't like what his word says, others don't want to surrender to anyone. But there are others who have felt like God abandoned them or that he was unable to protect or deliever them from certain difficulties. Isaiah explains that our God isn't crafted by the imaginations of men. It was mankind whom God created. And God is just as powerful today as he was while Isaiah spoke to Judah.
