A recovery of a thoroughgoing doctrine of Original Sin is, indeed, of utmost necessity in this hour.
From this doctrine God reveals to us that we aren’t rising out of the pond scum and into perfection. Rather, we have fallen from the glorious heights of the good way in which God first made us. Only by Christ, the Perfect Man, can we rise and be restored to goodness. Always remember that the Good News of the gospel is prefaced with the bad news of our fallen condition. Any other starting point is trying to imprison you forever in hell.
