From a theo-dramatic perspective, however, the sending of the Son has more to do with enacting than encoding. For the Son’s mission is not simply to convey information (though revealing the Father is an aspect of his work) but to convey the personal promise, presence, and power of God. Similarly, the words of the Bible are not simply carriers of information but means of transformation. The gnostics (and others since then) erred precisely at this point, in thinking that salvation was a matter of knowledge only. If that were the case, then information alone could save us. But it is not the case. Hence the sender/reciever model offers only an abbreviated picture of what happens in the communicative act; it does not account for the illocutionary and perlocutionary dimensions of God’s word.
