Gods covenant faithfulness

Ps 36 4 Even on his bed he plots evil; he commits himself to a sinful course and does not reject what is wrong.

5 Your love, O LORD, reaches to the heavens, your faithfulness to the skies."

These two verses are contrasting freedom that God establishes and the ultimate problem of preventing freedom that comes from the heart of man. This is really the basis of the teaching about inability. Man is finite and is unable to promote freedom at the highest level. "Not rejecting what is wrong" is not being able to put oneself on Gods level of substitution for someone else. The Psalms focus on this as the central problem of the presents of corruption in this world. It is not that man does things that are morally wrong but that man is unable to promote the highest good of his neighbor because of his corruption. 

The Psalmist doesnt even introduce this contrast of " Your love O Lord" with a idea that ties these contrast together but he breaks into the contrast with praise as if he is saying that Gods kingdom is real reality as opposed to this world system which is an illusion. He is saying that if God were not sovereign there would be no freedom because there would be no presence of eternal faithfulness.  

What is the ultimate solution for man being reduced to the level of the philosophy of the survival of the fittest? The Psalms speak of this world that is full of corruption as man being reduced to surviving like the beast of the field. Because man is unable to establish freedom on this earth in an eternal sense then God must act according to His covenant to recreate it by blessing and cursing. God establishes the highest order in life and He reaches down to through the curse to uphold His elect when they are at their lowest. "6 Your righteousness is like the mighty mountains, your justice like the great deep. O LORD, you preserve both man and beast."
