Let's think back to the start of the Church… in 1st Century Christianity by looking at the book of (Acts). It’s helpful to know that the book covers about 30-years of time. It shows us the start of the church and how the Gospel spread. Some have called it the bridge between the Gospel of Jesus and the Epistles of the Apostles. The Holy Spirit created a sound like rushing wind (Acts 2:2) which drew the attention of the city, and Peter ends up speaking to the crowd (Acts 2:14). In (v.41) We see 3,000 people from this crowd respond to the Gospel. People changed their outlook & opinions for something better! And in (v.38) they asked what they should do!?! Peter says repent and be baptized!
