The church I attended years ago asked us to pray and ask God what to pledge to support the church. A month later we put the $ or % figure on a pledge card, signed them, put them into a basket, and offered them to the Lord. This happened once a year. They didn't teach on giving or tithing.
Later, within a period of a month or two, the Lord supernaturally led me to all the scriptures on tithing. I soon realized tithing's a bible pattern. When I asked Him about it. He said, "Tithing pleases Me". I checked out my finances and 10% wasn't doable. I couldn't pay my bills. He told me to trust Him, so I began tithing and the financial miracles started happening.
I've had money appear several times in my bank account, that couldn't be traced back to a source.
I've found large sums of money in envelopes, or in strange places at home.
I've had unexpected checks and refunds appear, in the mail or on my credit card.
I've had people (some of them strangers) hand me money.
God give me my first business supernaturally. I was unemployed and looking for work. I'd just bought a house and had huge bills. God had strangers phone me asking for a quote. They couldn't explain how they got my private number. I prayed, got a business name, and registered it quickly after this happened several times.
The interesting thing is each time I had a job interview, a call came to do a job. I prayed and felt earning immediate cash for a job was more important than showing up for an interview. After 3 or 4 months I realized I had a prosperous business and stopped looking for a regular job.
I didn't miss a bill or my tithe. God provided supernaturally for each need.
