Here is a quote from Wigglesworth:
I know a man who was full of the Holy Ghost and would preach only when he knew that he was mightily unctionized by the power of God. He was asked to preach at a Methodist church. He was staying at the minister’s house and he said, “You go on to church and I will follow.” The place was packed with people and this man did not turn up and the Methodist minister, becoming anxious, sent his little girl to inquire why he did not come. As she came to the bedroom door she heard him crying out three times, “I will not go.” She went bark and reported that she heard the man say three times that he would not go. The minister was troubled about it, but almost immediately after this the man came in, and, as he preached that night, the power of God was tremendously manifested. The preacher asked him, “Why did you tell my daughter that you were not coming?” He answered, “I know when I am filled. I am an ordinary man and I told the Lord that I dared not go and would not go until He gave me a fresh filling of the Spirit. The moment the glory filled me and overflowed I came to the meeting.”
May we all desire that kind of anointing!
