What the Bible says about Self
(From Forerunner Commentary)
The Pharisee glories in what he is ("I am not like other men"), what he does ("I fast twice a week"), and what he gives ("I give tithes of all that I possess"). Self is a prominent feature of his prayer—he uses the personal pronoun "I" five times—showing his great obsession with himself. He does not pray for others, and frankly, he has no interest in them other than to point out their faults. Not satisfied with commending himself, he disdains the tax collector as well, when he should have interceded for him before God. His prayer shows that he thinks of God as being impressed with pettiness and severity.
