In a statement he said that the people of York has responded "with tremendous spirit, resolve, and generosity, to the plight of their flooded neighbours at this time."
The Archbishop released his prayer for everyone affected: "Here is a prayer you may wish to use at this time of flooding:
"O Lord our God, our very present help in time of trouble,
"Hear our prayers for all those whose homes and businesses have been flooded.
"May they know the care of friends and neighbours,
"And the blessing of supportive communities.
"Bless all those of our emergency services seeking to help those affected.
"We thank you for their commitment, compassion, and courage.
"Keep them safe from danger, and sustain them for their task.
"Make us alert to the needs of others, and show us what we ourselves can do to help.
"Though the storms rage, the rains fall, and the rivers rise, may we hold fast to love, hope and faith, and work together for the good of all.
"We ask this in the name of our Lord Jesus, our Saviour, Rescuer, and Lord.
"Amen."
He has been speaking as 93 flood alerts remain in England and Wales, including 27 severe flood warnings in place across northern England, meaning there is a danger to life.
Dr John Sentamu said that: "Between Christmas and the New Year this has been particularly difficult for individuals and families, many of whom will have been completely unprepared for the inundation which is currently happening.
"Besides the shock and danger of the floods themselves, for those flooded out, the drying time and clean-up period will be long, tedious, costly, and sheer hard work.
"It is no surprise, however, to see the people of York responding with tremendous spirit, resolve, and generosity, to the plight of their flooded neighbours at this time. The City Council, the Emergency Services, and a great army of volunteers are rising to the challenge with characteristic courage and compassion.
"I want to express my thanks and appreciation to all those who are giving up their time to help and care for those who have been flooded out. You are our modern day Good Samaritans –I salute your readiness to respond to your neighbour's need."
He continued and spoke about flood defences in the city: "I know that a lot of work has gone into making more robust the flood defences in the City of York over recent years – it will be all the more disappointing to those who have laboured to achieve this, that we have not been able to prevent another serious flood in our beloved City."
The Archbishop concluded, saying that people can help in any way they see fit: "Be sure, there will be opportunities for people to respond generously to those in need – financially, with practical assistance, food, accommodation, and moral support."
