You mean your Moslem clerics do not receive any income from their ministries? How do they pay their bills?
Are you saying Paul was Wrong?
1Co 9:7 Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock?
1Co 9:8 Say I these things as a man? or saith not the law the same also?
1Co 9:9 For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?
1Co 9:10 Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope.
1Co 9:11 If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things?
You say Jesus was wrong....
Mat 10:10 Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.
Whether you agree with Paul and Jesus or not, do you read what they said? Do you see what they said?
