So, the appropriate question is ... are we in need of "reviving"? Are we satisfied with what we are? Always the same fights, the age-old disagreements? There is no need to revive a living, conscious man. The living do not require a resurrection, neither are the righteous compelled to repentance. So ... is this living, or what? Is the constant bickering, fussing, and snarling amongst ourselves righteous and tolerable, what we enjoy with contentment?
If you do what you have always done, you will always get what you have always gotten.
Yes, an emphasis on revival is needed when the need for revival is present. We need the preaching of an Isaiah amidst the rise of idolatry, the weeping of a Jeremiah when sin takes society across the line, the demonstrations of an Ezekiel when Judgment is come, and the hope of a Daniel when the present is so dark.
