Tim Challies has a 2 part series at his blog on the issue of giving. In it, he answers 4 questions:
1. Do I have to give some of my money away?
2. What should be my attitude as I give money away?
3. Where am I to give?
4. How much am I to give?
I found Challies' succinct answers to these questions to be very helpful. In summary, he shows that as Christians we are indeed to give money away. We are to give cheerfully, mainly to our local church. And, we are to give sacrificially, where we actually feel that it is costing us something to give. He closes the series by showing that the tithe (giving 10% of our income) is meant to be a starting point for giving generously.
So, as you prepare for the new year, evaluate your own giving and plan to generously invest in the Kingdom of God in 2012. No greater investment can be made.
