Appearances? Charisma? Size and numbers?
“I have made a fool of myself, but you drove me to it. I ought to have been commended by you, for I am not in the least inferior to the ‘super-apostles’, even though I am nothing. I persevered in demonstrating among you the marks of a true apostle, including signs, wonders and miracles. How were you inferior to the other churches, except that I was never a burden to you? Forgive me this wrong!” 2 Corinthians 12:11-13
The genuine often feel embarrassed at self-promotion or the possibility of it.
The genuine often serve sacrificially and in secret.
The genuine is marked by patience as they serve God without recognition or appreciation.
The Church had experienced the authentic apostleship of Paul but were still being swayed by the loud self-promotion of those who only claimed they were an apostle.
It is still the same today.
It is possible that those whose focus is only that of marketing their self-declared ministries actually have little substance. Whereas sometimes the genuine can hardly be seen.
It could be that what impresses you is fake and what you have missed is the genuine.

Dear Paul, When you hit a nail correctly you really can hear it, and larger nails sometimes ring as they are struck (often only two or three times) home. I’m saying in a round about way, direct hit! Thank you, Richard
