Lent, of course, is a time where we think about sin – original sin and sin in general. Since our problem with sin began in a garden, maybe it makes sense to use a garden analogy.
God calls us, but we are not always sure what we are hearing. And even then, He calls us to follow, but not always to know where we are going. Scripture is filled with callings: Abraham, Moses, David, the prophets, the Apostles, St. Paul ... they were called, but they did not know the way. They had to trust God who called them.
