Jesus went about asking us to repent, to change our ways and believe in the Gospel, the good news. The Spirit led Jesus into the desert. Mark tells us that the Spirit drove him into the desert, and he remained there for forty days, tempted by Satan.
It was only after John had been arrested that Jesus began proclaiming that the Kingdom of God is at hand and all needed to repent, to change their ways and believe in the gospel.
Lent is a time to change our lifestyle for God's Kingdom is here. We are to go out and spread the good news by our own lives; by our compassion and love. The pope is urging us to go out to others. We are to show the same love and compassion to others as Jesus shows - it is the love of Jesus that we reveal and bring to others.
