Teaching in India

They (i.e., RIMI) finally started getting some details to me about my trip to India. We had already agreed that for the first week I will teach in their satellite school in Rajasthan. My theme there will be "Principles of Worship." I think I already asked for some input on this theme, and I'll just note that the response to that request has truly been underwhelming!

So, I'll try getting some response on what I'm starting to think of for my topic/theme for the second week. Initially, Laura (my contact at RIMI) thought I would be teaching on Ephesians for the 2nd week--as will all the speakers. Now she learned that I'm free to teach on whatever theme I want to (was there something in the reference letters sent in on my behalf that prompted this change? [that's a joke]). So in my Bible study time this morning, God seemed to open up to me a concept that I think could be helpful. We (bw & I) had prayed about this a few times that God would direct my thinking about such a topic.

So, I'm thinking I'll teach on something like "Prevailing against the Gates of Hell." With that as a centering thought, I will look at the lessons from various events from the OT when the people of God stood against incredible odds. E.g., this morning I was copying the story of David and Goliath. (Who are the "Philistines" and/or "Goliaths" for Indian believers?)

So here's my request to you (I'm hoping for a slightly LESS underwhelming response on this one): What other occasions (preferably OT) can you think of when the people of God faced overwhelming odds, but God gave the victory?

So (I just figured since I've been using "So" at the start of each paragraph why stop now?), if you pass along such an event from OT, the next question is: What lessons can we draw from those accounts? And how can those relate to God's people in India where they live among 800million Hindus and 200million Muslims?

Thanks for your help!
