Luk 18:10-14
Two men went up into the temple to pray; the one a Pharisee, and the other a publican.
The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.
I fast twice in the week, I give tithes of all that I possess.
And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.
I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.
This is a great parable told by Jesus for people who thought themselves righteous. Today, to be true, we Christians resemble the Pharisee. We blow our own trumpets even if we have done something little religious or righteous. There are many church denominations who claim themselves as pure and the only chosen bride of Christ thereby belittling other fellow Christians. We think ourselves righteous by our acts and fail to acknowledge the Grace of God through which we are made righteous. (Eph 2:8-9 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.)
Let us stop boasting of our works and always humble ourselves in the presence of God.
We need a change in our attitude for our prayers to be heard.
