Same source as below – here are (according to Jim Packer) some defining signs of an authentic revival:

God comes down.

God’s Word pierces.

Man’s sin is seen.

Christ’s cross is valued.

Change goes deep.

Love breaks out.

Joy fills hearts.

Each church becomes itself—becomes, that is, the people of the divine presence in an experiential, as distinct from merely notional, sense.

The lost are found.

Satan keeps pace.

Not really liking the phrasing of the first one – creates too much of a ‘distant God above’ theology that flies in the face of His omnipresence and immanence.

Not quite sure what he meant at number 8?
