MamaMary, you need to take a deep breath, find a quiet place, and sit down with that Bible.
Open up to 1 Samuel 16 and read how King David is chosen
Then Samuel asked Jesse, “Are these all the sons you have?” Jesse replied, “There is still the youngest, but he is tending the sheep.” Samuel said to Jesse, “Send for him; we will not sit down to eat until he arrives here.” Jesse had the young man brought to them. He was ruddy, a youth with beautiful eyes, and good looking. The LORD said: There—anoint him, for this is the one! (1 Samuel 16:11-12)
David’s six brothers are all in the tent, hoping to be chosen as the next king. They are anxious, trying to be noticed, vying for attention, and actively seeking the glory of the kingship. David on the other hand is faithful to his work. His head is down and he is doing his job quietly, and that is when God calls him.
All through the Bible, God chooses people who are quietly doing what they are supposed to be doing, not anxious over the future.
Jacob is the perfect example. He is described as “A quiet man, dwelling in tents”. Jacob is obedient to his mother but Jocob’s brother Esau is restless, always out hunting. Quiet hardworking, obedient and humble Jacob gets the birthright and the blessing. Esau gets nothing.
As he was walking by the Sea of Galilee, he saw two brothers, Simon who is called Peter, and his brother Andrew, casting a net into the sea; they were fishermen. He said to them, “Come after me, and I will make you fishers of men.” At once they left their nets and followed him. He walked along from there and saw two other brothers, James, the son of Zebedee, and his brother John. They were in a boat, with their father Zebedee, mending their nets. He called them, and immediately they left their boat and their father and followed him. (Matthew 4:18-22)
Peter, Andrew, James and John were doing what they were supposed to be doing, not looking around anxious about the future, not restless, but attending to the business at hand according to their station in life at that time, feeding their families and tending to their needs. And that is when they are called.
All through the Bible, God calls those who quiety work, who do a good job and work hard, are obedient to their superiors, those who take care of their family, and who are not restless and always looking for the next thing.
Study hard at school. Enjoy summer. Read that Bible. Think about college. Get a spiritual director. Frequent the sacraments. Go to Mass as often as you can. Get involved in your parish and find a way to serve - be an altar server or help the poor. And open up a conversation with your parish pastor who will get you in touch with the vocations director at your diocese - they can guide you.
But for now, consider the lessons of the men who quietly did what they were supposed to do and then were called to greatness. And consider our Lord, who though he was God, was obedient to his Mother Mary and his Father Joseph, working as a carpenter, until his hour came.
