God has spoken through His prophets, and ultimately through His Son, Jesus Christ. There is no further revelation needed. By His Spirit, He continues to lead those who look to Him, and by this method, God has spoken to me as well (not as new revelation, but as a fellowship, Spirit to spirit). I don't mean to offend, but whatever experience you had (and I don't deny you had an experience) holds no particlar interest to me. I know who God is; I know His name; I know His character; I've read of His actions within history; I know of His actions toward me; and by His Spirit, He communicates His character to me and through me (as He does with all who have expressed faith in Him and look to Him for guidance and life). What does your testimony offer that I have not already experienced through Jesus Christ?
So, if I understand what you're saying, you're telling God to shut up?
Because that is what you are saying. You're demanding that God say nothing that He hasn't already said. You're saying that the Author wrote His book and He's not permitted to write any more.
What arrogant, hubristic, prideful folly.
