The Nationwide Christian Trust, CARE, Maranatha and Gideons have united to send the politicians a number of documents which encourage them to look to ensure Christian values are put into all the different laws.
They want Christians to sign up to commit to regularly praying for the MPs and in turn will send out a prayer guide every three months explaining some of the issues that are being discussed in Parliament
Ray George, from the Nationwide Christian Trust said: "We are losing the strands of Christian values in Parliament.
"If this continues we will see continually things happening which affect our country.
"We've sent out 650 folders... with a Bible, a document called rebuilding Christian Britain then a letter [from each of the organisations]."
