Because, just like Patrick, we are called to be missionaries in our own age. When Patrick landed in Ireland in 432, he had been tasked by the Holy Spirit with evangelizing a pagan people. He was not afraid because he was filled with the Holy Spirit. Then, he won the next generation by preaching the Gospel without compromise and letting the Holy Spirit work in and through him. The same God Patrick served is pouring out His Spirit today, calling Christians to mission in the Third Christian Millennium.
