Knowing God more by God's word and experience

Acts 11:11-18
John baptized with water, you will be baptized with the Holy Spirit. Peter remembered Jesus words.
If God gave them the same gift as he gave us, who believed in the Lord Jesus Christ, who was I to think that I could oppose God?
When they heard this, they had no further objections and praised God, saying,"So then, God has granted even the Gentiles repentance unto life."
Luke makes it clear that the apostles and leaders fully approves Peter's action, the hand of God was so evident in it all.
Why?
Peter wanted to prove that all these phenomenon were given by the Lord, and proved it with Jesus word.
Experience with God's word may assure that it is the truth.
How?
We may meet new matters or new experience, with God's word we may know more about the Lord.
