This was Peter speaking to the Jews and people that were in Jerusalem. He was showing them the answer to become closer to God. This still applies today! Can you feel the Holy Spirit with you? Have you accepted Jesus Christ as your savior for your sins? There were 3,000 lives saved that night. What an amazing work of God! He showed Peter and Joel what to say in order for them to make an impact on the lives they touched. He will do them same for you and I if we talk with him and get to know him better! Help be a follower of Christ and help lead others to him!
