Their new report, called 'Good news for the poor?', found nearly four out of five evangelicals thought the last government's economic policies did not benefit the most needy.
Lucy Olofinjana is a Research Coordinator at the Evangelical Alliance. She told Premier the majority of evangelicals think the Bible teaches they should work for justice for the poor.
She told Premier: "Evangelicals are really active in tackling poverty in lots of ways, so seven in ten have donated in a food bank in the last year and almost four in ten are volunteering with a Christian poverty project of some kind.
"There's really a sense that people feel this is a mandate from God.
"97 per cent, so almost everybody who took our survey said that we should be working for justice for the poor and that we all have a duty.
"And also a sense that we will be judged if we are not working for the poor."
She said the desire to help is motivated by a belief that God is on the side of the poor, and 86 per cent think they will be judged harshly if we neglect to care for those less fortunate.

Commenting on the report's release, Dr Dave Landrum, director of advocacy at the Evangelical Alliance, said: "Evangelicals are active in tackling poverty and they're disappointed at the record of the government over the past five years.
"As ever, we're committed to working with charities and local government to help those in our neediest neighbourhoods.
"We want to see a society that provides opportunities for people to work and to have access to the education and training necessary to be able to avoid or escape poverty.
"The government not only needs to value and support the work of churches, it also has a responsibility to make sure that poverty decreases and doesn't increase in the next five years."
