Here are a couple of resources I discovered in preparation for the message Living Single in a Married World delivered at Bethany Place based on Philippians 1:12-30. It was an unusual text to use for this subject. The audio should post soon. The most important resource I want to point out is a talk given by Tim Keller called Singleness: The Biblical Guidelines. However, it does deal with mature subject matter. Another blog post of interest is What Not to Say to Single Women in Your Church
I also used the following quote from C.S. Lewis. It is found in The Weight of Glory
It would seem that Our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.
