Acts 10:44-45
44While Peter was still speaking these words, the Holy Spirit fell upon all those who heard the word.
45And those of the circumcision who believed were astonished, as many as came with Peter, because the gift of the Holy Spirit had been poured out on the Gentiles also.
1 Corinthians 2:1-5
1And I, brethren, when I came to you, did not come with excellence of speech or of wisdom declaring to you the testimony of God.
2For I determined not to know anything among you except Jesus Christ and Him crucified.
3I was with you in weakness, in fear, and in much trembling.
4And my speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power,
5that your faith should not be in the wisdom of men but in the power of God.
