Friends and co-workers of Millard Fuller, the co-founder of Habitat for Humanity, celebrated his life this past weekend.

Through Habitat and his latest organization, the Fuller Center for Housing, he helped build homes for low-income people around the world.

Former President Jimmy Carter helped fuller build hundreds of those homes. He spoke of his recent visit to Fuller's gravesite.

"As we stood by his grave, the most modest grave I'd ever seen and we silently thanked Millard Fuller for changing our lives and letting us understand what a Christian could do in a practical way by putting our faith into practice," Carter recalled.

After the ceremony, the crowd marched to a nearby home that had been destroyed in a tornado one year ago and started rebuilding it.

They said it was the best way to remember Fuller's life. He died last month of an anuerysm at the age 74.
