Job opportunity: Prayer needed

I have wonderful friends who are encouraging and have been talking me up to other educators in order to help me find a job. One of their friends at the parent play group works at an upscale preschool in the Garden District and she called me to see if I was interested in taking a job with them. I am extremely flattered to be considered (not that I have decided to take the job) because it is an amazing school with an outstanding reputation.

My dilemma in deciding whether or not to take this job is that I feel called to work with and advocate for low income families who are less likely to know the resources available to them. I don't know if working with low income families is what I need to be seeking after right now or if the job offer at the preschool is an opportunity to make an income for a semester while figuring out exactly where God wants me. I'm afraid that I will take the preschool job and get too comfortable working in a familiar environment instead of seeking an opportunity to work with low income families. Please pray that God will guide me in my decision making and make it clear where he wants me for this season of my life.
