Should Christians Tithe 10% During Hard Times?

The issue of tithing during tough times has taken center stage since New Orleans Saints reserve quarterback Mark Brunell, a former Jaguars tosser, declared bankruptcy in June... His legal filing revealed that despite his financial woes, Brunell gave $155,000 of his $1.55 million salary to his Jacksonville church....Brunell’s tithing was welcome news to many pastors.

 The subject of tithing will always bring about great debate...You have a number of  Christians believing you should always give  10% of your  income to the church no matter what....And the other half saying no way...Some Christians are asking  should  the  tithe  10% still be a requirement even  during economy hard times? Some believe strongly that it should , as Scripture says...What do you think? Do you tithe to your church?
Should the paying of tithe be an option during hard times?
