Trust in God's word doesn't mean we won't have moments of uncertainty, disappointment and bewilderment.
Official English summary of Pope Francis’ Wednesday catechesis on hope:
Dear Brothers and Sisters:
Our continuing catechesis on Christian hope leads us in these Christmas days to consider the example of Abraham, who, as Saint Paul tells us, “hoped against hope” in God’s promises.
Trusting in the Lord’s word that a son would be born to him, Abraham left his home for a new land. Although the fulfillment of God’s promise was long delayed and seemed to be impossible, Abraham continued to hope. Even his discouragement and complaints were a sign of his continuing trust in God. Abraham, our father in faith, shows us that sure trust in God’s word does not mean that we will not have moments of uncertainty, disappointment and bewilderment. It was at such a moment that God appeared to Abraham, called him forth from his tent and showed him the night sky shining with countless stars, assuring him that such would be the number of his descendants. Hope is always directed to the future, to the fulfillment of God’s promises.
May the example of Abraham teach us not be afraid to go out from our own tents, our limited outlooks, and to lift our eyes to the stars.
