"Each of you must repent for your sins and turn to God and be baptised in the name of Jesus Christ for the forgiveness of your sins.Then you will receive the gift of the Holy Spirit."
A crowd gathered, and Peter Addressed them. He preached to them of Repentence and the Gospel. He told them of baptism.
On the day the Holy Spirit descended, 3000 people were baptised and joined the church. This is why we celebrate Pentecost.
Because the Holy Spirit enabled the apostles to speak differentlanguages, they were able to spread the Word of God. The peoplethat were baptized on Pentecost were then able to spread theWord of God to others. Now, the Church has millions of followers around the world
