Then you obviously deny what Jesus said:

Truly, truly, I tell you, he who believes in me, the works that I do, he will do also; and he will do greater works than these, because I am going to the Father.
-- John 14:12

and to the hearing from God, there are many verses, for example:

My sheep hear my voice, and I know them, and they follow me
-- Jonh 10:27
