God usually doesn't give us instructions in an audible voice. The Bible teaches us that God speaks to us through an unction from the Holy Spirit. For lack of a better phrase, we will have a feeling from God that leads us to do a particular thing. This means we have to interpret that feeling to find the correct course of action God desires for us take. Therefore, we have to be very careful not to allow our traditions (i.e., the way we have always seen things done) misinterpret an unction from God.
