The scriptures are a recipe for getting into the presence of the Lord. Like recipes in a cook book, they are not the meal, but directions for getting the meal. Big difference. He is the meal, the truth. The recipe is true, which means that if you do what is written, you get what is promised. But it is not the truth, a source of words on any subject that you can bet your whole life on. That would be Jesus Himself.
Now, God tells me that He will keep the promise of testing Him in Malachi, where tithing brings prosperity, for any human being who attempts it as such. And, any effort to tell any non-tither that they are thieves, robbing God, He will meet with conviction. Of course, believers who are giving beyond the tithe will be comforted. He encourages dealing with anyone in destitute poverty with this message, that they may prosper. (Probably deluded) believers who give at below tithing levels ought to check in with Him about their salvation.
Now, the issue of "having" to tithe for salvation is not on my table. That's not what He tells me is involved in "keeping the least of the law and the prophets, and so teaching others," (Matthew 5:19) which, He says, I can do if I aspire to be great in His Kingdom. The point is that there is wisdom and life in the law, and we do well to ask Him what word from His mouth we might obey to keep any and all of the law. The lawless forget this, He says, and He says that He doesn't know them, where they are coming from, what their spiritual agenda is. He understands those who are looking for ideas to solve problems, wisdom, and want to include both Him and His law in the process.
I am pleased to hear that you know His voice, but in judging myself, whenever I catch myself saying what I did NOT hear, I retreat as quickly as possible to my prayer closet. No one cares what we do not hear, except someone praying for our soul as one who gives an account, who wants to know when we have fallen into spiritual trouble. We are admonished to share what we do hear.
God said that he intended for all nations to be blessed through Abraham's descendants bringing the law to all. The law was a major step in delivering any and all peoples from the nastier aspects of slavery to Satan, and for tutoring that brings to Christ. Nothing about it is arbitrary, and all of it, as wisdom, brings a measure of salvation, as abundantly as one sows into it. But, the law itself says to obey God's voice, asking about the law. There is little encouragement to obey the law itself.
If such faithful tithing brings increase to my master's house, and rids it of the devourer, as it fact it does, why not? But the fervent effectual prayer of the righteous is more profitable.
