The communication which God has made to man is true, but that does not mean it is exhaustive. This is an important distinction which we must always bear in mind. To know anything exhaustively we would need to be infinite, as God is. Even in Heaven we shall not be this. God has communicated to man, not only about the cosmos and history, but also about Himself. And God’s attributes so communicated are meaningful to God, the author of the communication, as well as to man, the recipient of the communication.
The God who has created man in His own image communicates true truth about Himself. Therefore, this need not be thought of as only an existential experience or contentless “religious ideas.” We have true knowledge, for as the Scriptures say so simply and overwhelmingly, when God wrote the Ten Commandments on stone, or when Jesus spoke to Paul on the Damascus road in the Hebrew language, a real language was used subject to grammars and lexicons, a language to be understood.
The biblical presentation indicates that because man is made in God’s image, the problem of God communicating to him is not of an absolutely different order from that of man speaking to man. We are finite, God is infinite, but we can understand truly.
