To complain to God in moments of doubt and fear like Abraham is not something bad, but rather is a form of prayer that requires the courage to hope beyond all hope, Pope Francis has said.

While in life there may be times of frustration and darkness, "hope is still there and it moves us forward," the Pope said during his weekly general audience.

"I won't say that Abraham loses patience, but he complains to the Lord. This is what we learn from our father Abraham: complaining to the Lord is a form of prayer. Sometimes I hear confessions where people say, 'I complained to the Lord.' But no. to complain; he is a father and this is a form of prayer. Complain to the Lord, this is good," he said.
