In today's Gospel from Mark 1 at Mass, we heard that Jesus, passing by the Sea of Galilee, saw Simon and his brother Andrew casting their nets into the sea; they were fisherman. Jesus said to them, "Come after me, and I will make you fishers of men." They left their nets and followed him. He walked along a little farther and saw James, the son of Zebedee, and his brother John. They too were in a boat mending their nets. Then he called them. So they left their father Zebedee in the boat.
Although we cannot hear the physical voice of the Lord today; nevertheless, you can be sure that he still calls us through other means. It's the same voice that speaks directly to the heart. Anytime the Lord calls us, he is calling us to live with him for all eternity! Our only right response is to follow him without reservation.
