A Calvinist is a person who knows he is bad, and knows Christ is good. It's that simple.
In this series I have endeavored to show how a Biblical understanding of human depravity leads directly and necessarily toward a theological viewpoint which exalts the grace and mercy of God, maximally glorifies Him, and gladly rejoices in His exhaustive, meticulous, comprehensive, detailed, enveloping, all-encompassing sovereignty over all things - including the salvation of individual sinners. The five parts coincide with the 5 points of Calvinism.
The trouble with some Calvinists is they have forgotten they are bad. A "good" Calvinist (indeed, a "good" Christian of any sort) has a short shelf life and spoils immediately. Bad Christians, on the other hand, never stop repenting and never stop receiving more of Christ and grace. And when Christ's work in us is complete, we will be fully restored from all the effects of the fall - better than if it had never happened.
Soli Deo Gloria!
