I read the website Need To Be Debt Free, and think they are working really hard in pursuit of getting out of debt. They made over $10k net last month in income by working 2 jobs and overtime at their primary jobs. They worked something like 12-16 hours a day. I don't know if I could make that sacrifice to get out of debt by losing time spent with my family, but I do understand.
Anyway though, they mention a lot about tithing. Any extra money they make they tithe, or give 10%. I think it's fine, but I have suggested that they donate their time in exchange of money so they can get out debt faster and thus spend more time at the church and with family. I suggested that they divide the amount of money they feel they owe by their hourly rate and help the church by making flyer, stuffing envelopes, cleaning, cutting grass, basically anything.
Sure we donate money to charities monthly. But personally I don't find it very satisfying. The bigger satisfaction comes from actually going to the food bank and physically helping out. Or going to the woman's shelter and donating goods and helping them organize the goods. Those feel so much better.
Our roommate is a devout muslim and faithfully donates Zagat (muslim tithe and it's 12.5%). Anyway he also teaches Sunday School and helps out with prayers. The Zagat is a starting place, but he gives more time because he feels it's important.
Thus I do understand being loyal and having to give God 10%, but is tithing just because you have to? If it's not just because you have to, then why aren't you going out and helping the church above and beyond the money? Why aren't you donating more time?
