Jesus said; ye are the light of the word,,  let ur light so shine before men that they may see ur good works and give God glory.

Another passage states: A man's gift find a way for him and make him stand before kings.

Jesus also said; come unto me all ye that are labor and heavy laden I will give you rest
That was a bublic declaration. And Jesus was well known for his acts (miracles) because he's always willing to do miracles

Jesus also said without signs and wonders men will not believe

As we all know that information is very important becouse it gives direction, if miracles are not made known to the public by pastors, people will not have a clear direction of where to get a solution to their problems they might take a wrong step. God delight in solving problems (miracles)

Considering the points above, I think there is nothing wrong in advertising miracles (it's an information that has to be passed across because miracles are the act of God)

I will put the vehicle to a stop by the word of my mouth, in Jesus name
and then help the guy in any way I can

The truth is; by all standards, the church of God can not be poor. Remember the popular saying “Givers never lack” this is a reality, a universal law it is, irrespective of who you are or what you are. The more we honestly give the more we receive and the more the gospel is preached (Church growth). I am very sure the givers do not complain but none-givers do because they could not understand how the givers get more to give (it’s a law)

Luke 6:38. Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.

John 12:24. Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.

Note that no body is compelled to give or go to church, it’s a personal decision. So the government can not decide the extent of what and how one can give thereby can not regulate the church finance because the givers are the factors of church growth.

I will rather advise all the church leaders to remember the early church (none of them lack) and that the money is strictly meant for the propagation of the gospel and to bless humanity not for a selfish purpose. Everyone shall be judged according to their works
