On Try a Tithe Sunday the Stewardship committee is simply asking the congregation to give a tithe for that week and test if it is plausible for them. Better yet to try giving a tithe one Sunday a month.

Ezekiel 20:39-40, Choicest Gifts
As for you, O house of Israel, thus says the Lord God: Go serve your idols, everyone of you now and hereafter, if you will not listen to me; but my holy name you shall no more profane with your gifts and your idols. For on my holy mountain, the mountain height of Israel, says the Lord God, there all the house of Israel, all of them, shall serve me in the land; there I will accept them, and there I will require your contributions and the choicest of your gifts, with all your sacred things.
