After Jesus' ascension, the apostles gathered in an upper room, anguished and unsure about the future. Suddenly, a sound like a strong wind filled the place, and tongues of fire appeared above their heads, symbolizing the arrival of the Holy Spirit. Full of courage and wisdom, they began to speak in different languages, proclaiming the wonders of God. Crowds gathered, marveling at what they saw and heard, and many were touched by the message of divine love. Thus, Pentecost became the milestone of the beginning of evangelization, uniting Christ's followers in a new mission.
