I am only a man myself

Acts 10:17-33
While Peter was still thinking about the vision, the Spirit said to him, “Simon, three men are looking for you. So get up and go downstairs. Do not hesitate to go with them, for I have sent them.”
As Peter entered the house, Cornelius met him and fell at his feet in reverence. But Peter made him get up. “Stand up,” he said, “I am only a man myself.”
He said to them: “You are well aware that it is against our law for a Jew to associate with or visit a Gentile. But God has shown me that I should not call anyone impure or unclean.
But when the men from Cornelius arrive, he is quick to realize the far deeper human implications of his dream. 
Peter's hunger, and perhaps the leather awning overhead(遮陽篷), shape the images of a vision which God uses to convey his message.
Why?
All of these are the Holy Spirit speaking to Peter to let him know the message of the Lord.
Cornelius met him and fell at his feet in reverence. but Peter said, “Stand up,” he said, “I am only a man myself.”. Yes all of us are a man only. We are sinners, but trust in Jesus Christ and accepted by Holy Spirit.
Because of Peter, so the Holy Spirit said to Peter three times. For Peter has higher authority among apostles.
How?
Be humble, even have many miracles as Peter, I am a man myself. God is my king, Jesus Christ is my savior.
