Agree with both.
God makes use of the entire world to speak with us. The ability to commune directly with God is the divine birthright of man. Satanists are those causing man to forget this.
Even Christians must account for how Christ, who was perfect man, spoke with the Father. I know most Christians imagine some kind of innate sense, but it is clear from his exclamation on the cross ("Father, Father, why have you abandoned me?" -he couldn't be abandoned unless he could previously sense God's presence), Christ as man knew himself to be in the Father's presence. What Christ knew, and was teaching to his disciples, was how to commune with God. It was knowledge meant for everyone.
God might speak as a burning bush, as silence, or even through the mouth of man.
