The Holy Spirit came! The proof was not just what “devout [Jews] from every nation under heaven” (2:5) saw as a result of the Spirit filling the hundred and twenty. It was much more than that! Peter, who had difficulty saying anything right, was suddenly preaching with accuracy in the Scriptures and convicting power in the Spirit (2:14-36). Peter and John used a Jewish prayer service to heal a man lame from birth (3:1-10). This is followed by questions from the religious crowd as to how these things could be, which led to another clear proclamation of the gospel.
But there was one observation the Jewish leaders made that helped answer their astonishment. “They recognized that they had been with Jesus” (4:13). Do you think they were only referring to what happened before Pentecost? I am convinced not! “And behold, I am with you always, to the end of the age” (Matthew 28:20). In the giving of the Holy Spirit, God the Father was providing the presence of Jesus Christ with His own as they walked with Him by the Spirit.
Does this describe your daily walk with Jesus?
