INTRODUCTION Jeremiah 17:9 says of our hearts, ‘The heart is deceitful above all things, and desperately sick; who can understand it?’ Our hearts are self-deceiving, in other words we lie to ourselves. We deceive ourselves about many things but two stand out in our text today. We lie to ourselves about our own goodness; and we lie to ourselves about others sinfulness. We come another famous parable of Christ in Luke 18:9-14, the parable of the Pharisee and the Tax Collector. Jesus has been speaking about how we ought to persevere in prayer, this parable too is about prayer. Jesus here teaches us the proper attitude that makes us and our prayers acceptable to God.
