Approaches to Whole Life Stewardship

I did an assignment regarding several approaches to stewardship. Four approaches included self centered, self sacrificing, good intentioned, and biblical. I found myself laying in the biblical approach most of the time, with the exception of the money area. I find myself leaning more towards the saving aspect of money, rather than having a better balance between making, giving, and saving. I feel like it is very important to save "for a rainy day", because it seems like we have had a lot of those lately. The problem is that in my quest to save some money, I might be neglecting the opportunities Christ is presenting me to further his kingdom with my income. Lord, grant me the wisdom to know when to save and when to give!
