My question is motivated by the following excerpt from William Lane Craig's Reasonable Faith article The Witness of the Holy Spirit:
Plantinga's model involves crucially what is usually called the inner witness of the Holy Spirit. In his model the Holy Spirit functions on the analogy of a cognitive faculty, producing beliefs in us. I myself prefer to think of the Spirit's witness either as a form of literal testimony or else as part of the experiential circumstances which serve to ground belief in God and the great truths of the Gospel. In either case His deliverances are properly basic.
I have characterized the witness of God's Holy Spirit as self-authenticating. As I explain in Reasonable Faith,
By that I mean that the experience of the Holy Spirit is veridical and unmistakable (though not necessarily irresistible or indubitable) for him who has it; that such a person does not need supplementary arguments or evidence in order to know and to know with confidence that he is in fact experiencing the Spirit of God; that such experience does not function in this case as a premiss in any argument from religious experience to God, but rather is the immediate experiencing of God himself; that in certain contexts the experience of the Holy Spirit will imply the apprehension of certain truths of the Christian religion, such as "God exists," "I am condemned by God," "I am reconciled to God," "Christ lives in me," and so forth; that such an experience provides one not only with a subjective assurance of Christianity's truth, but with objective knowledge of that truth; and that arguments and evidence incompatible with that truth are overwhelmed by the experience of the Holy Spirit for him who attends fully to it.
Notice the sentences in bold "experiencing the Spirit of God", "the immediate experiencing of God himself" and "the experience of the Holy Spirit". It is evident that William Lane Craig believes that God can be directly experienced by Christians in a self-authenticating, veridical and unmistakable manner.
Question: Are there other well-known Christian authors who hold similar views to William Lane Craig regarding the supposed ability of Christians to have access to a direct, truthful, and unmistakable self-authenticating experience of God?
Also, is this a fringe view or a common view among Christians?
