The Search said " God does not (as far as I am aware) go beyond the things that are written, and audibly speak with certain humans" I would like to direct your attention to the following scripture from acts.
Act 11:28 And there stood up one of them named Agabus, and signified by the Spirit that there should be great dearth throughout all the world: which came to pass in the days of Claudius Caesar.
God does indeed speak to people in the New Testament. He always has, there were many prophets in the bible who could be enquired of by kings etc. I am not saying I am a prophet but rather God still speaks to me from time to time. The bible also says:
Mar 16:17-18 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
Miracles should be the normal thing for a Christia,n to not see them generally means the person is not dedicated to God, that the person does not spend enough effort to really know God.
