Geisler and Nix have very interesting facts check this out.

Several alternatives were open to God in His choice of a means for communication of His truth to men. As a matter of fact, a wide variety of the media of communication were actually utilized by God “in time past,” as He “spake unto the fathers by the prophets” (Heb. 1:1, KJV).

What God Could Have Used

God could have chosen to continue to communicate with men as He did initially in biblical times.
Sometimes God spoke through angels (Cf. Gen. 18-19, 22; Ex. 3.) In fact, their very name means “messenger.” Their ministry began in Genesis (chaps. 18–19), and continued through the very last chapter of the Bible (Rev. 22:8-9).[Page 322] However, the very nature of their celestial intrusion into the terrestrial made it a special revelation that did not lend itself to permanence. There were certain distinct limitations in having to call upon angels to convey everything that God wished to say to every man under every circumstance in every age. One could imagine quite an endless invasion from outer space in order to care for all the details of truth transmitted to billions of people, many of which have short memories.

Visions and dreams This was another means of communication that God occasionally chose to utilize (cf. Dan. 7:1; Gen. 41). Visions and dreams had more potential for universality and individuality than did angels. This is because it did not involve the mass of heavenly traffic and it could even be worked into one’s personal experience more readily. However, this method also has serious handicaps. For one thing, visions and dreams tend to be subjective and personal rather than objective and universal. For another, even their ecstatic impact could wear off and be forgotten.

The Urim and Thummim and the lot These methods were sometimes used to determine God’s will (see Ex. 28:30; Prov. 16:33). However, they were limited in the scope of the content of truth they could convey. Apparently, all they could indicate was a yes or no answer to questions that men happened to direct toward God. Thus, their scope was quite limited when compared with a detailed description of God’s declarations to men found in other media of transmission.

The moral law and creation God has revealed Himself by the moral law “written in the heart” (Rom. 2:15) as well as through creation (Ps. 19:1 ff.) to all men. But the amount of truth available here is limited and subject to corruption. Romans 1:18-19 says that although the truth from creation is “evident within them,” men “suppress the truth in unrighteousness.” Their consciences also distort the moral law (Rom. 2:15; cf. 1 Tim. 4:2). Further, even though this general revelation is sufficient for man’s condemnation (Rom. 1:20; 2:12), only through special revelation has salvation come to light (Heb. 1:1; Rom. 10:9 f.).

The audible voice and the direct miracle These were also media of divine communication (see 1 Sam. 3 and Judges 6:40), but they suffered from the same intrinsic difficulties that other means had, namely, they were good ways for God to speak to one man on one occasion and for one specific purpose. Nevertheless, it would be a strain on the divine economy to expect a repeat performance of these feats in speaking to all men everywhere. This is not to say that all of these methods were not good; they were in fact the ways by which God did speak to the prophets. There was, however, a better way to[Page 323] communicate; it was a more precise,
