I believe that you are being short sighted about it, Brother. You posted some good scriptures too and I'm not saying they are not true, however, I'll post a few myself for your perusal which may give you something to think about.
Mark 16:
14 Later He appeared to the eleven as they sat at the table; and He rebuked their unbelief and hardness of heart, because they did not believe those who had seen Him after He had risen. 15 And He said to them, “Go into all the world and preach the gospel to every creature. 16 He who believes and is baptized will be saved; but he who does not believe will be condemned.
17 And these signs will follow those who [d]believe: In My name they will cast out demons; they will speak with new tongues; 18 they[e] will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.”.../
So Jesus spoke to His disciples after his resurection about signs, and, "those who Believe"
Granted many times in history after that it could be said, no one believes anymore...but that's not really true. Because there's always a remnant at least. So if signs and wonders went away with the Apostles then believers had to go away too.
John 14:
12 “Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater
works than these he will do, because I go to My Father. 13 And whatever you ask in My name, that I will do, that the Father may be glorified in the Son. 14 If you [
c]ask anything in My name, I will do
it.../
This is Jesus talking again... Jesus doesn't specify Apostles, He says "he who believes". That's me! That's You!
You should pray about if you should put more stock in people's testimony's.
