Almost three weeks ago I stopped eating and started fasting, calling people of faith and conscience to do the same.
At the height of the Civil War in 1863, President Abraham Lincoln issued a proclamation calling the nation to a day of fasting, prayer, and what he called, "national humiliation." Taking his clues from the biblical prophet Isaiah, he argued that the twin national sins of slavery and war required nothing less than collective lamentation and corporate repentance.
"Woe to those who make unjust laws, to those who issue oppressive decrees, to deprive the poor of their rights and withhold justice from the oppressed of my people, making widows their prey and robbing the fatherless," thunders Isaiah in chapter 10  only later offering a vision for national repentance in chapter 58 , uttering words that national leaders ignore at their peril:
Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter -- when you see the naked, to clothe them, and not to turn away from your own flesh and blood? Then your light will break forth like the dawn, and your healing will quickly appear.
Invoking these biblical themes, Lincoln's message was clear: God judges entire nations, not only individual citizens, according to their participation in God's best hopes and dreams for the world. Isaiah, like the rest of Hebrew prophets, says justice for poor people is a huge part of this vision. It's not only the litmus test of a nation's righteousness; it's the essence of true worship.
Nearly 150 years after the Civil War, America's sins are different, but as citizens -- especially Christian citizens -- I believe the times again cry out for our national humiliation, specifically, for the ways we treat those who Jesus called "the least of these."
In 1993, as a member of Congress, I fasted for 22 days, water only, to protest the lack of conscience of the U.S. Congress towards poor and hungry people. Now, almost 20 years later, the stakes are even higher, with Congress proposing budget cuts  that will hurt the poor even more than the cuts that provoked me to fast and pray two decades ago.
Budgets are moral documents. They reflect the priorities of individuals, households, and even nations, exposing our real notions of who and what is valuable. As elected leaders in Washington engage in shouting matches over how to solve America's looming sovereign debt crisis, the voice of the poor is still getting drowned out. They're obviously not our priority.
Every day 25,000 people worldwide die from hunger and preventable diseases. 50 million Americans  go to bed hungry at least two or three times a month; 17 million of them are children. So when I saw a recent poll  showing that my fellow evangelicals were among those most supportive of cuts to foreign aid directly benefiting vulnerable people, it broke my heart.
Those who believe the government should not be involved in helping poor people have a spiritual obligation to restructure the missions budgets of their churches and reevaluate their own giving priorities if they want their views to be taken seriously.
Like President Lincoln before, I believe that America now faces a monumental crisis of conscience. The proposed cuts undermine America's values and -- for those of us who aspire to follow the life and teachings of Jesus Christ -- should offend our sense of what it means to be a Christian, especially if we believe God will judge nations based on how they treat the poor.
America faces tough choices about the long term fiscal health of our nation, but we shouldn't balance the budget on the backs of poor and hungry  people. I respect Paul Ryan for putting serious deficit reduction back on the public agenda, but his proposal goes too far in slashing funding for vital programs that ensure millions of Americans don't go hungry and that literally save lives around the world.
I believe fasting, when done with the right heart and the right motive, gets God's attention -- which is why I'm fasting along with more than 36,000 Americans and 28 members of Congress who have already joined the movement. Hopefully this fast also gets the attention of politicians who would balance the budget on the backs of the poor. It's time to call on God.
