We established that the evidence of the baptism of the Holy Spirit in the disciples was accompanied by their sanctification, prophesying, visions, dreaming dreams and signs and wonders. While Acts 2 does not indicate all of them directly, Peter mentioned all of the elements of Joel’s prophecy when he responded to the Jews’ surprise at the event (Acts 2: 16-22). This implies that he and the disciples were manifesting all of these signs and evidences. Another evidence of the baptism is that Peter suddenly received spiritual revelation and was able to expound the scriptures/prophecies about Jesus, David as if he was a rabbi. He preached a long message and people were convicted or pricked in their heart (Acts 2:37). This led to the salvation of about 3000 souls (what % increase was that? They started with 120 in Acts 1: 15). Unprecedented numbers of salvations or number of people believing the truth will take place when the power of the Holy Spirit is manifested in the lives of believers. Note that the disciples were preaching to religious people in this instance. No one will be able to deny the truth of the preached word of God, particularly when it was accompanied by a feat outside of the natural ability of the speakers. This was the speaking of the prophesies, visions etc in languages that were not native to the speakers. This is one sign that Joel spoke of. Speaking in tongues is a good sign to look but is not the only sign of the baptism of the Holy Spirit. The Lord says we must remember that there are also tongues of angels (1 Cor 13:1) and that tongues (of men) are for the unbeliever as spoken of by Paul (1 Cor 14: 22). Tongues are given as a sign to the unbeliever that God knows their language and that He is hearing them when they speak. He uses tongues of men to establish contact with people who do not believe the gospel and who need to hear it, just like He did on the day of Pentecost when He interrupted the Jew’s formal ceremonies that did not bring salvation in order to point them to salvation and life. Other evidences of the baptism or outpouring were long term and evidenced in Acts 2: 41-47. There was steadfastness in the doctrine, even though their understanding of the truth was still limited. People continued to receive the truth and believe in Jesus as Savior. There was a spirit of praise in the body of Christ. Signs and wonders proliferated, the people shared their possessions, the had holy communion regularly and were in favor. Blessings
