The event of the coming of the Holy Spirit changed the lives of the apostles. They were no longer afraid to speak about Jesus. They became bold and on fire with zeal and commitment to proclaim the good news to every creature. And this is also what the Holy Spirit does to us - He ignites the flames of our burning heart for the love of God.
Let us pray that we may sustain the fire in our hearts through constant prayer and devotion, obedience to the Church, and our humble imitation of Mary - Mother of the Church.
