Evangelical author and radio host Joni Eareckson Tada will be speaking at Thursday's 60th annual National Day of Prayer.

Eareckson Tada, who was paralyzed in 1967 following a diving accident, said she hopes her involvement will highlight war veterans wounded in Iraq and Afghanistan.

"It's our military who bear these wounds of conflicts. These people really have my heart and I think I bring that unique perspective as a person with a disability," she said. Eareckson Tada was chosen to serve on the 2011 Honorary Chairman, National Day of Prayer Task Force.

The day was first set aside in 1952 by a joint resolution of Congress and the bill was signed by President Harry Truman.

This year's theme is "A Mighty Fortress is Our God," taken from Psalm 91 in the Bible's Old Testament.

Shirley Dobson, chairperson of the National Day of Prayer, appeared on Tuesday's "The 700 Club" to talk more about this year's theme, prayer points, and what local communities can do to become involved in the annual Day of Prayer.
