Today is the Feast of St. Andrew, Apostle. The Gospel from Matthew 4 read tells that Jesus, walking by the Sea of Galilee, saw the two brothers Simon and Andrew casting a net into the sea and said to them, "Come after me, and I will make you fishers of men." At once they left their nets and followed him. Today's Communion antiphon, John 1.41-42 ~ Andrew told his brother Simon: We have found the Messiah, the Christ. Then he brought him to Jesus.
If we hear the Lord calling us personally, we must realize that it's going to be the beginning of a most intimate relationship, a most blessed journey. With God, there's no place for casual relationships.
