1. The self-righteous Pharisee (9-12)
Jesus told this parable to those who compare themselves with others and think that they are a little better. This Pharisee thought he was worthy of being heard. The self-righteous person who prays to God and expects to be answered on the basis of his own merit does not know God, and does not know himself.
2. The sinner (13-14)
Tax collectors were public sinners. This man had no illusions about himself. He came to God as a sinner, asking only the mercy of God. He knew that the righteous God is merciful to sinners who repent. He prayed the prayer that God always hears and answers: 'God, have mercy on me, a sinner.' God forgives and exalts those who come to him like this.
Application: Lord, I come to you just as I am. I am nothing but dust and ashes, but you are righteous and merciful. I come because you have promised to receive and forgive sinners for Jesus' sake.
One Word: God hears the sinner's prayer
