“Then Jesus told this story to some who had great confidence in their own righteousness and scorned everyone else: “Two men went to the Temple to pray. One was a Pharisee, and the other was a despised tax collector. 11 The Pharisee stood by himself and prayed this prayer: ‘I thank you, God, that I am not a sinner like everyone else. For I don’t cheat, I don’t sin, and I don’t commit adultery. I’m certainly not like that tax collector! I fast twice a week, and I give you a tenth of my income.’
“But the tax collector stood at a distance and dared not even lift his eyes to heaven as he prayed. Instead, he beat his chest in sorrow, saying, ‘O God, be merciful to me, for I am a sinner.’ I tell you, this sinner, not the Pharisee, returned home justified before God. For those who exalt themselves will be humbled, and those who humble themselves will be exalted.” Luke 18:9-14, New Living Translation
People without religious are self-righteous in that they look to themselves for meaning, peace, and salvation. Christians can also be self-righteous and in some ways, this is even worse because self-righteousness is antithetical to the Christ’s way.
The only cure for self-righteousness is to reflect or meditate on the cross of Christ. Dr. John Stott once wrote:
Our sin must be extremely horrible. Nothing reveals the gravity of sin like the cross. For ultimately what sent Christ there was neither the greed of Judas, nor the envy of the priests, nor the vacillating cowardice of Pilate, but our own greed, envy, cowardice and other sins, and Christ’s resolve in love and mercy to bear their judgment and so put them away. It is impossible for us to face Christ’s cross with integrity and not to feel ashamed of ourselves. Apathy, selfishness and complacency blossom everywhere in the world except at the cross. There these noxious weeds shrivel and die. They are seen for the tatty, poisonous things they are. For if there was no way by which the righteous God could righteously forgive our unrighteousness, except that he should bear it himself in Christ, it must be serious indeed. It is only when we see this that, stripped of our self-righteousness and self-satisfaction, we are ready to put our trust in Jesus Christ as the Saviour we urgently need. — John Stott, From “The Cross of Christ”
