"No, thank you." My wife and I taught our girls to say those words whenever they don't want something. It is polite and reasonable to use such language when you are offered something that you have no desire for.
Our youngest is 2 years old (today! Happy birthday, sweetheart!), and she has learned her lesson in manners well: whenever it is time for her to go to bed and she isn't agreeing, or when it is time for her to be punished because she has disobeyed, she will immediately tear up and cry, "No, thank you!" All this in hope that we will accept her polite refusal and offer her some alternative to the proceedings.
The sinner is no different; he hears the Law, and he sees its eternal, holy and absolute rule over his life. He sees Christ, offered once for all; the sinless One for sinners slain. The sinner scoffs and says, "no, thank you", all the while hoping beyond hope that his choice is a valid one and that some other escape can be managed from out of God's sight. The depraved heart of man desperately wants to hear that his attempts to clear his own name are somehow reasonable. He wants so much to have the chance to define his own destiny in eternity, and he will scrabble for every bit of nice, flowery-sounding language he can find to dress up his pitiful cries.
"No," says the reprobate, "thank you, but no. I will not have God as Ruler of my life. I will instead be reasonable and accommodating, insofar as it serves my purposes. I will not be beholden to anyone over me, as that would require me to owe them something. No, thank you; please take away this Law that convicts and in its stead kindly provide pluralism and sincerity where Truth used to reign." Evolutionism, Universalism and Romanism all allow for the same thing: the opportunity to mold and shape one's life as one pleases while attending with totally false sincerity to a form of 'godliness' that is nothing more than window-dressing. After all, what is the value of 'godliness' if the 'god' you are trying to conform to is nothing more than an understanding and shape-shifting enabler who most certainly sees religion as each man's private business?
Never mind, then, this Sovereign God Who is above all things and has ordered all things according to His own will and counsel! Give us, the world cries, our own rule, and allow us to bend, break and even do away with standards of truth of any kind whenever they conflict with our pleasure in this world! Give us, beyond this life, a God and an eternity wherein are people and spiritual concepts that make the eyes misty and populate the sympathy-card racks at the stationery store! But a God Who has spoken, and it will come to pass? A Lord of Heaven and earth to Whom everyone shall bow? "No, thank you."
Eternal God, take our pride and all the shallow and hollow platitudes that we have been clinging to. Replace them, I pray, with the Light that illuminates first our great and utter sinfulness and then Christ as Redeemer in all His glory. Render silent all the voices within us that would encourage our rebellion, and in Thy great grace make known to us our bondage without You and liberty within You. All this through and because of Christ the Savior. Amen.

Have you ever used aromatic oils or scented candles in your home? My family has. The fragrance in those oils and candles comes from the ESSENTIAL chemicals found in nature. For example, the ESSENCE of vanilla is extracted from the bean in such a way that the fragrance is maintained and the scent is produced without having to keep the physical plant around, because it would rot and the bean or leaf would burn improperly for the effect one desires. I once worked in a warehouse where, besides all the finished products containing essential oils and fragrances, there was also kept gallons and gallons of the actual essential oils, ready to be sold to manufacturers of cosmetic products.
How many times have we heard from people (or said ourselves), "Mankind is ESSENTIALLY good and moral"? As was described above, the ESSENCE of something is the source of it, or where it comes from. The Word of God says that "out of the abundance of the heart, the mouth speaketh". In short, the essence of mankind is the source from which his 'fragrance' comes. Has a man ever lied? Cheated? Stolen? Been unfaithful to marriage or contractual vows? God's word tells us that a tree cannot produce both good and bad fruit, so what do the actions of men say about their ESSENCE, or the core of who and what they are? The leaves, or outward appearance, may be showing green, as did the leaves of the fig tree in the Gospel account, but there is no fruit to be had from a tree that is corrupt. The outward good appearance of the actions of men cannot hide the fact that at their core is corruption and wickedness. We may hide our barren state under piles of green leaves, but upon examination, the ESSENCE of mankind is fruitlessness altogether. God Almighty, upon Thy mercy we cast our barren selves and admit by Thy grace what is true; we have no soundness or wholeness to our flesh whatever, and all our pretended righteousnesses are as filthy rags. Spare us, O God, and not for our sake, but for the sake of Christ Jesus and His holy and perfect sacrifice in payment for sin. Christ and Christ alone is able by His almighty power to make all things new, and so to Christ alone we cling and entreat Thee from His loving arms that Thou wouldst stay Thy hand of judgment and instead honor Thy Son with a posterity that is clothed in His righteousness. For all this we ask in and through and because of Christ Jesus. Amen.
