Tithing is law. Believers are free from the law and, yet, seek to meet it in spirit and truth. That is, we are free to give or not but fools if we do not yield all we possess to the Lord.
Having said that, I do not believe in supporting the ‘works’ of the modern church as you describe. Salaries, bills, insurance and (worst of all) mortgages for million dollar temples. Feed the hungry, care for the sick, provide for the widows and fatherless. A simple look around today will provide more opportunities to give of yourself and your resources than you could meet in a lifetime.
Let the bulk of idiocy in modern ‘Christian’ culture find its own financing.
I am sympathetic to your point of view, but this doesn’t mean that one doesn’t give at all, it just means that the tithe goes to another Christian cause. No?
