back to Jerusalem movement - great army of God in the last days

I just finished reading the "Heavenly Man" book (just 1 month ago). I read how brother Yun had a vision from God to start this movement.

I was amazed that God would use such a man at such a decade as
ours (reading how his testimony and the life of Chinese Christians perfectly pictures New Testament Christianity in the Book of Acts).

I don't know where this would lead to but surely if God is in the lead then we Christians might be used by God to have a part on it.
