You said, "I use the principle of tithing with my income to give back to God what He has freely given me."
The principle of tithing, if there even is one, was NEVER giving back to God anything. You have the principle wrong; thus, your conclusion is wrong.
I will explain again. God NEVER asked or commanded anyone to give back to Him a portion of what man earns. That is an insult to God. God RESERVED a tenth of crops and animals from His increase, and directed that tenth be taken to the Levites.
How anyone can come up with a principle of giving back to God what one earns from the Biblical tithe is beyond my comprehension. It isn't logical, and merely proves my point that pastors who teach tithing has corrupted God's Word.
NO pastor ever taught tithing on one's income until 1870.
Say what you want. Believe what you want. Fact is, you aren't tithing to God. You are giving a tenth of your income to an organized corporate business doing business as a "church." That is not giving to God to begin with. Just more lies from pastors.
Jesus told us the only way to give to Him is by giving to the poor/needy. Jesus NEVER said giving to the church is giving to Him.
It is obvious you are not open to studying the scriptures, but rather have your belief and will stick to it no matter what the scriptures say.
Unfortunately, since I am a Money & Finance Minister, and have discussed tithing with many pastors of many different denominations, I have learned from my own experience that some even admit to me that they know there is no Christian tithing, but they teach it anyway because it brings in more money. Pastors have admitted to me that the flat out lie to their members.
It is sad, but I don't trust what a pastors says any more than I trust what a used-car salesman says. Too many are liars.
Not all denominations teach tithing, and not all pastors of even a denomination like Baptist teach tithing. Most do, but some are knowledgeable, honest pastors who teach truth and won't compromise God's Word for any reason.
Today, ALL born-again believers are priests. ALL of us are called to be deciples of the Lord. No one of us is higher than another. Our bodies are the Temple where the Spirit dwells. According to the scriptures, priests do not tithe. Trying to tithe today shows a denial that you are a part of this Royal Priesthood. It also denies what Jesus did on the cross. While you are trying to show appreciation and thanks to God, you are actually doing the opposite. Good thing God knows your intentions are good.
