This is not what the Bible says. Where does it tell you to do this? Giving is not worth anything in the eyes of God unless it is done in the way prescribed by God. And he tells in the rules for the grain fields;
You are to reap only enough that you can live through the day. And you are not to take the first fruits at all. The rest, you leave alone just in case somebody poorer than yourself wanders by and needs feeding.
When you give money, you likely earned that money by way of focusing on your own personal wealth, which is also referred to as the beast. The flesh. When you give money and take a tax deduction; you have merely given away somebody's nameless money, as much connection as you have to funding a sweat shop when you buy shoes.
When you give service, and you are in any way compensated or have nothing better to do; it is not the Spirit of love. Love is all God ever wants of anyone, because faith follows. The human heart is all evil, all the time. The mind is stupid, all the time. And so the rules set forth in the Bible for charity and love are mandatory for it to be seen in his eyes. We have altered definitions and accepted lies over time, but the Bible's word will always overrule our ideas and feelings.
If it is not sacrifice, it is not love. If it is not love, it is empty. I suggest you open, and read, and do not think, and do not do other than what your savior and owner has asked of a very much willing and free slave. If nothing else, Paul's letters to the people who were trying to be good at that time, too.
Like I said different people, different opinions. My post, my opinion.
Who said anything about opinion? I have no horse in this race. I am relaying no man's opinion.
