Tithing is Biblical, and from what I understand so far, it was 10 % of what we have, not what we hope to have.
The problem I see about this is not the tithe, its with the people tithing .
You have good church's and bad church's .Lets called these churches trees producing fruit . Some are edible, some are so bad, they cannot be eaten .
Lets say these fruit are figs, there are two kinds of figs male figs, which are not edible ,they taste bad, then there are the female figs, which are edible, like the Smyrna fig tree.
And lets compare the tithing church members to little fig wasps; the way the fig's are pollinated.
The wasp files to the nearest fig ; that is giving off chemical signals released when it's ready for pollination, and enters the fig , while it also lays its eggs there, in the process it losses its wings and antenna .
The fig wasp can't tell the difference between the good or the bad fig. You can blame the stupid wasp, for allowing the bad fig to get its start and continue with the little eggs that begin to hatch from the bad fig, and the cycle continues .
You have to mature where your fed ALL, of God's Word, as it is presented word for word,chapter by chapter an verse by verse in the Bible .
Anything less, is a bad fruit. And if you support that, look what Christ said of some of those bad churches in Revelation . There was only two kinds that are going to make it. And those two are Not waiting to be flown away in rapture.
If your tithing to a church Christ is going to fight against, your not going to be blessed for that.
