From The Response website:

Historic Response

As a nation, we must come together, call upon Jesus to guide us through unprecedented struggles, and thank Him for the blessings of freedom we so richly enjoy according to His grace, mercy, and kindness towards us. A historic crisis facing our nation and threatening our future demands a historic response from the church. We must, as a people, return to the faith and hope of our fathers. The ancient paths of great men were blazed in prayer – the humility of the truly great men of history was revealed in their recognition of the power and might of Jesus to save all who call on His great name.

Muslims, Jews, Hindus, Buddhists, Atheists need not apply.
