In our society today where marketing and advertising is the only way to bring customer or create awareness about your business or organisation, but is the church also suppose to engage itself in advertising testimonies in hand bill or palm flirt just to bring more members or worshippers to the church?,or to make people believe that their church have done more miracles than others?. These questions I ask but seems to find no answer about about the church advertising testimonies, but, let me tell you why the church don't need to advertise testimonies. An example is the traditional religion, the traditional religion have never for one day advertise their gods or on television or advertising testimonies one who their gods have help or how many people the gods have set free from bandage, but still this gods shrine get more client everyday in respective of weather it is advertise or not.
Another example is Islam, if the Muslim tell you what Allah have done in their life, you will be shock to hear their testimonies, but have they ever advertise those on television before or even sharing hand bill talking about testimony ? I guess you know the answer which is NO because it is not necessary.
The Indians believe in philosophy called (palmtiesm) meaning that there is a spirit leaving in an element, which means, stone, water, sun, wind, etc has it own spirit that lives in it and if you start worshipping that element it will work for you, that is why today Indians worship anything, including images of a dead person, Indians also worship cow, goat, rat, etc, but the Indians never comes our to advertise how their gods have help a lot of people, because it is not necessary.
Now let get down to Christianity why do churches do advert about how their members have been heal or how somebody have been suffering from a particular sickness but immediately he/she step foot in their church they became heal, for example if you go to the apostolic church, Christ apostolic church, cherubim and seraphim church, Roman catholic church, the Anglican church, Jehovah witness has no central owner, you will discover that they never publish or promote or advertise testimonies because it is not necessary but other churches that have a central owner like, synagogue of all nation, Christ embassy, redeem christian church God, mountain of fire, triumphant christian church, winners chapel etc always advertise testimonies like it's only their church that God leaves.
It is bad for a church especially most pentecoster church with central owner to advertise testimony because there is no religion or church that don't have testimonies, the bible make us to understand that where two to three people are gather that he is always present in their midst, so please if your church is involve in this acts, tell your that it's bad and necessary for the church to advertise testimony because God leaves every where.
But I think testimony should be allowed cos it's a way of appreciating to God for his goodness
