Honesty, yes this reminds me of an essay I saved - it applies to those who think it is possible to work for salvation, or earn salvation, which of course is anti-biblical. Sorry its a bit long. Let me know if anyone wants the full version. That is what I believe the Bible means by self righteous:
So how can you, a sinner, stand justified before God?
And behold, a certain lawyer stood up and put Him to the test, saying, "Teacher, what shall I do to inherit eternal life?" And He said to him, "What is written in the Law? How does it read to you?" And he answered and said, "You shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself." And He said to him, "You have answered correctly; do this, and you will live." (Luke 10:25-28, NASB)
"Do this and you will live." Keep God's law perfectly, never sin, and always obey Him in everything with all of yourself. Your heart, soul, strength, and mind must be perfectly expended in obedient love to God and to your neighbor. No losing heart in time of trial. No weakness in work. No wandering thoughts leading to sin. Every fiber of your being expended in love for God and this perfectly. "Do this and you will live." This is the perfect and holy law of the perfect and holy God. But is this good news? Did the lawyer who answered the Lord rejoice in this? Did he go away feeling self-righteous, thinking that he certainly had a good standing before God? After all, he was trying his very best to obey these two great commandments.
Note the next verse. (But wishing to justify himself, he said to Jesus, "and who is my neighbor?" John 10:29, NASB) Self-righteousness raises it's ugly head here. "Wishing to justify himself." But note, God's law is not based on "our best efforts" or "our good intentions" to keep it. You really, truly have to keep it! Perfectly! "Do this, and you will live." Not "Try to do this." Not "Give it your best shot." No, one single failure, one disobedient act, one sinful thought, one omission of any kind, one failure is fatal. Yet this expert in the law was "wishing to justify himself."
In case you remain unconvinced let's look at another man "wishing to justify himself" in his own self-righteousness.
And as He [Jesus] was setting out on a journey, a man ran up to Him and knelt before Him, and began asking Him, "Good Teacher, what shall I do to inherit eternal life?" And Jesus said to him, "Why do you call Me good? No one is good except God alone. "You know the commandments, 'Do not murder, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and mother.'" And he said to Him, "Teacher, I have kept all these things from my youth up." And looking at him, Jesus felt a love for him, and said to him, "One thing you lack: go and sell all you possess, and give to the poor, and you shall have treasure in heaven; and come, follow Me." But at these words his face fell, and he went away grieved, for he was one who owned much property. (Mark 10:17-22, NASB)
The Lord of the universe rehearsed with this man the requirements of the Law. What is his answer? "I have kept all these things from my youth up." Wrong! He missed it. He didn't get it. His eyes were blind, his heart was cold. He did not hear the Lord that day, but wishing to justify himself, he condemned himself by his own words.
Now I wonder, do you hear the Lord right now? "Do not murder (or be angry with your brother without cause). Do not commit adultery (or look lustfully on another). Do not steal (or envy another). Do not bear false witness (or lie)." Can you even meet the first requirement of the law mentioned here, let alone law upon law upon law?
Don't think that Jesus was giving the man an opportunity to justify himself before God through obeying these laws. The Lord here was not implying that the man had actually followed these nor could he follow them. Jesus was using the law to demonstrate to the rich man his utter sinfulness; his total, complete poverty of any righteousness, and thus His need of a savior. He had broken every one of these commandments (as we all have - either in thought or in deed). But did the man hear? Did he really hear what the Lord said? No, even though he had physical ears and heard Jesus' words, God had not yet given him "eyes to see and ears to hear". No, he thought he had kept these commandments of God. He remained in darkness. Instead of answering "I have broken each of these countless times. How can I find righteousness before God? God, be merciful to me the sinner!" Instead of that kind of answer, he broadcasts his spiritual blindness. "Teacher, I have kept all these from my youth up."
I expect that some of the people reading this are like these men. You wish to justify yourself in the sight of God. Your answer to the Lord would run along the same lines and that answer would miss the mark of God's righteousness to your damnation. Instead of justifying yourself, you condemn yourself by your own words.
If the Lord were to question you now, "Why should I let you into heaven?" Will you venture your answer by starting your sentence with "I...". Or perhaps you would even be bold enough to say, "Lord, I...". You are seeking to justify yourself. You are standing on your own righteousness. To do so, even in part, even in small part, is to be self-righteous and self- condemning. The road to hell starts in your own heart with that one little word "I". I hope and pray that this tiny word leading to an eternity of separation from God would not be found on any of your lips. Oh that the Lord would open your eyes and ears today that you would hear His words and see your condition as it is.
Because by the works of the Law no flesh will be justified in His sight; for through the law comes the knowledge of sin. (Romans 3:20, NASB)
