No, read Luke 18:9-14. Does the OSAS Proponent fit the description of the Pharisee or the Tax Collector?
13 “But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, ‘God, have mercy on me, a sinner.’
14 “I tell you that this man, rather than the other, went home justified before God. For all those who exalt themselves will be humbled, and those who humble themselves will be exalted.”
So what did the one that has admitted that is a sinner has done? The other is in denial.
