why exodus 15?

I was fired on a Sunday a few months back. To be clear, I was at fault, whether my mistake deserved termination I disagree with, but I did make a mistake. Since then I have struggled to understand God and the lessons he would have me to learn.

I have a decent work history, one I am proud of, but it is now mid September and I have yet to find work within my chosen field. Sure I have a job, it pays a little over half what I need to make, and that is only if I got the hours I was promised and not the half I have been getting. I am married with children, my wife works part time and makes the money in the family. We are losing our house, sheriffs sale in October. Why am I writing all this? Well, because the blog is called Exodus 15, and I am the wandering one, the reference has to do with Exodus 15:23-25.

And when they came to Marah, they could not drink of the waters of Marah for they were bitter: therefore the name of it was called Marah. And the people murmured against Moses, saying, What shall we drink? And he cried unto the Lord, and the Lord showed him a tree, which when he had cast into the waters, the waters were made sweet."—Exodus 15:23-25.

I am as one of the faithless faithful, wandering the wilderness going from worshipful adoration to faithless grumbling. This is my tale begging the Lord for bitter water made sweet.
