The Gospel tells us that the Spirit drove Jesus our into the desert. He remained there for forty days, tempted by Satan. Later, Jesus must have told his Apostles about these temptations. Mark does not go into detail but does tell us that the angels ministered to him. And then he tells us that Jesus, after John had been arrested, began to proclaim the Gospel: "This is the time of fulfillment. The Kingdom of God is at hand. Repent, and believe in the gospel."
We are still being called to repent and believe and this first Sunday of Lent is time to reflect on how we are living the Gospel.
Take some desert time today to be alone with Jesus.
