Romans 12:1-2; 1 John 2:15-16 

I was fishing for redfish in some unique water. It was salty enough that we caught redfish, a saltwater fish, but it was also fresh enough that we occasionally caught a large-mouthed bass, a freshwater fish. We were at a place near where fresh water flowed into the bay and formed an interesting mixture of the fresh and salty. Some mixtures, however, are not good, such a mixture occurs when we let the world system mix with our lives.
