Nowhere in scripture are we given any indication that God has ceased speaking to the church. In fact, the contrary is plainly indicated here:
Hebrews 12:22But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, 23To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, 24And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. 25See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven:
and here:
Acts 13:2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
You tell me how anybody could know what the Holy Ghost said if God doesn't speak in an audible voice in the church age.
You done come too late to tell me that God doesn't speak in an audible voice any more. I've already heard Him!
