These questions stir the pot, but are good to ask. I commend your bravery.
When the teachings of Jesus Christ are followed you will not be a popular person; therefore, to make money from the message will be slim.
Jesus Christ does not want us to follow after material things, but the eternal that will build moral and spiritual character.
Do you think that sell everything and give to the poor is a popular message?
The false teachers advertise by pulling peoples heartstrings by showing off their "good" deeds to increase or boost their reputation in order to increase their wealth and possessions. To do otherwise will ruffle feathers and cause dissension.
Do you think *advertising* your good works for the poor glorifies Jesus Christ, or boost one's ego?
Does the Gospel message dictate that we must advertise salvation to potential donors in order to raise more money for their charity?
The church today does not challenge the people because it will offend and effect bottom line of the "shareholders". The health and prosperity gospel leads to worship of the anti-Christ.
With that said, we cannot prove our faith, that is God's domain. God proves Himself to us, but we can provide evidence and sow seeds of the Good News.
If you are handsomely benefiting from the Gospel, it will be a message that is tickling the ears of the masses.
If I rephrased your question this way, it might shed a little more light on the subject.
Is Jesus Christ for sale?
“And as you go, preach, saying, ‘The kingdom of heaven is at hand.’ “Heal the sick, raise the dead, cleanse the lepers, cast out demons. Freely you received, freely give. “Do not acquire gold, or silver, or copper for your money belts - Matthew 10:7-9
