I appreciated your views expressed here in this article and wait to hear your new point of view. I also used to emphatically believe in these traditional tithing teachings. However, since I became a missionary my views on this teaching have turned 180 degrees. I had to repent of what I believed and entered into a new trust in relationship with God. I have had a total change of mind during the last 15 years while being a missionary in Europe and the USA.

3 sources I found that helped me through my questions were Dr Roger Sapps 3 book series. 1. Radical trust for God in Finances. 2. Miracles, Money and Motives. 3. The Children are Free. http://www.allnationsmin.org/SearchResult.aspx?CategoryID=4

There is also an article written by Ron Schwartz that helped to get a New Testament view on Ministry that is almost non exsistent in the Western Church.

And this article was also very beneficial - a look at the origins of tithing.

For me, obedience that results in pleasing the Father with all I possess and own is what is important to me now. God Bless you
