Maybe someone among us here is thinking: my sin is so great, I am as far from God as the younger son in the parable, my unbelief is like that of Thomas; I don’t have the courage to go back, to believe that God can welcome me and that he is waiting for me, of all people. But God is indeed waiting for you; he asks of you only the courage to go to him. How many times in my pastoral ministry have I heard it said: “Father, I have many sins”; and I have always pleaded: “Don’t be afraid, go to him, he is waiting for you, he will take care of everything.” We hear many offers from the world around us; but let us take up God’s offer instead: his is a caress of love. For God, we are not numbers, we are important, indeed we are the most important thing to him; even if we are sinners, we are what is closest to his heart.
