We are all called into "private ministry". And it is important to note that NOT EVERYONE is called into "public ministry". If indeed you are among the few that are called into public ministry, you should know this, deep down, on your inside. Many times, it will cost you a lot more, to wholeheartedly commit to the call to public ministry. This is a key reason why a very strong and reliable support base is needed. (Of course the celestials support but you need human beings to support you.)
For His public ministry, Jesus had a strong support base - His inner circle of Apostles and Evangelists. He also had some disciples, well wishers, etc. There were people who gave him moral support and prayed for Him and made donations to assist the work.
Our work of presenting the message of the Kingdom (Gospel Message) and the Fifth Epochal Revelation would gain greater traction when many more readers understand and appreciate these things.
