Concerning the visions and dreams of Joel 2:28....  The proof is based on my firsthand experience. It's how I found the new Messiah. I had dreams that led me to him. Once I met the new Messiah, I discovered his "disciples" had similar experiences.  Other confirmations:   When I asked God to use the bible to confirm that my dreams were authentic, I randomly opened the bible and it opened to my namesake. Doubting the chance coincidence I closed the bible and opened the bible again. It opened to the same passage. Still doubting, I closed the bible once more, took my hands off the bible, closed my eyes and tried again. Same thing. Same passage.    Years later, while listening to the new Messiah give a sermon, I doubted what he was saying about a certain bible passage. After the speech was over, I got a bible and opened it. (It was a huge bible. The kind found in seminary reference libraries). It opened straight to the passage and confirmed what he was saying was accurate.   This isn't to say the other people aren't destined to come to know the new Messiah if they don't have dreams or visions. I'm just sharing that we're beyond the 144,000 "firstfruits" phase of the "End Times." Thanks for asking.
