Norm Geisler and William E. Nix, evangelical theologians, have said that God speaks to us through angels, dreams, visions, miracles, nature, Urim and Thummim, casting lots and by studying other prophetic writings. He sometimes even speaks to us in an audible voice. Geisler and Nix add:
No doubt the most common method God used was the inner voice of the individual's conscience and communion with God. That is probably what is most often meant when the prophets write, "And the word of the Lord came unto me saying...."

Verbal inspiration (word-for-word dictation) is entirely possible for an omnipotent God, but Geisler and Nix are correct in saying that God more frequently allowed scriptural writers to exercise agency in choosing the exact words to use (Geisler and Nix, p. 55-58). This principle is just as true today as it was for writers of the Bible.
