With the help of more than 100 other people, Colin Grey completed the unfinished task his wife Joanne embarked on before she died nearly two and a half years ago.
Colin said: "Jo's faith and belief helped her in her physical battles and motivated her to continue stitching the prayer cards right up until she died.
"She felt very strongly that this was a task that God has given her to do and was her way of expressing support for our nation and Parliament and that prayer was vital in this."
Joanne, a developmental studies graduate from the University of East Anglia died from non-Hodgkin lymphoma in January 2015, aged 37.
During about the time of the MP's expenses scandal, she felt God gave her a vision to send cards to all MPs and peers.
Speaking to Premier during News Hour Colin explained his wife chose to include a quote from Proverbs 10:9, which reads: "He who walks purely walks securely, but he who walks in crooked ways will be found out."
Stitching right up to the hours in hospital before her death, Joanne made 731 cards. After an appeal for assistance, her husband Colin and a team of helpers have now completed all 1444 cards.
The Bishop of Norwich, Rt Rev Graham James said: "Colin was inspired by his late wife to continue her project to let every member of both Houses of Parliament know they are held in prayer.
"The prayer cards which have been produced, lovingly and carefully, have been done in appreciation of the public service of our MPs and Peers, assuring them of prayers for their work."
The cards will be given to all of the new MPs who return to Parliament after the General Election on June 8.
Colin added: "The idea was that people pray for the MPs and lords, Parliament and our nation while they were stitching.
"Her dying wish was that they are all completed and delivered. It is wonderful that her death has mobilized and inspired a network of people to do something practical and prayerful for our country."
