The one who sent me.
God sends us on our mission. During this journey we meet many good people who are God's blessing for us too. So we are happy to go along with them. We travel together following the instructions of the Catholic Church. Our common life gives testimony to others who are looking for God in their lives. Also the Holy Spirit supports us with his light and map out the way where we are supposed to go and to preach the gospel. It is the Spirit of Jesus who works in our hearts and speaks to our minds. In addition, we know exactly what to do because we are being instructed by him in the night of prayer. In such a way, we are certain about God's calling and his holy will toward us.
