In this Psalm we are being taught the perspective on evident inability. The Psalms teach inability accurately represents the proper attitude that we maintain as we rise up to the full effect of the curse. We are carefully instructed that Gods Law proportionally represents the considerable extent of the appropriate standard by which we live vicariously in objective reality. When sin entered the world we were not only subject to curse and moral darkness of the withdrawal of Gods blessing but were prevented from meeting the objective standard that we enjoyed in the garden. This functional perspective is absolutely essential in satisfying our frustration by the reasonable understanding of inability as we were issued a cold drink of sparkling water after we had run a marathon. The point is we are not reassured in the doctrine of inability teaching the law reports our sin, and we acknowledge our inability to fulfill it. That is falling back on moral guilt and being relieved by understanding that Christ work on our behalf demonstrates gracious acceptance. In this sense we are incapable to achieve genuine acceptance by what we do. But this is consistently remaining in the same step of conscious awareness. 

In the Psalms evident inability assigns us the protected right to appeal to God in the spirit of imputed justification that defines forgiveness and acceptance without us going through those steps. Because God is dealing with us graciously according to our limits and not the punishable violation. It is illustrated from this logic that God established the success of Israel through eliminating the nations who worshiped deceitful gods. Hence, God cleansed the nation of Israel, and the people were incapable to be tempted from those nations. In this logic every opposition that we encounter rises to the level of the intense curse. Because God acted appropriately to typically prevent Israel from destroying themselves by preventing their fierce temptation. God dealt with them as a people who were unable to prosper with active opposition. He dealt with Israel not according to their righteousness but their inability to withstand the longstanding opposition. Prov. 30 8 Keep falsehoods and lies far from me;give me neither poverty nor riches, but give me only my daily bread.9 Otherwise, I may have too much and disown you and say, 'Who is the LORD ?'Or I may become poor and steal,and so dishonor the name of my God."Solomon is teaching the power of the curse is moreover strong to overcome. To rise up to his intensest enjoyment in this life, he must not be prevented by the weight of the opposition in the curse. In this Psalm, David is complaining about the limits that he must endure because of the success and the propagation of filthy men.

The descriptive terms used about the social behavior of wicked men are constraining the enjoyable experience of God and his ability to fully prosper. He uses words like to fiercely assail, close up, track me down, like a lion hungry for helpless prey and surround me. You will invariably find that the Psalmist uses his sin as a frequent complaint because it is a moral weight that typically prevents him from his noteworthy success. Consequently, he considers his sin in the category of evident inability but the opposition of this world he aggressively implements the law in his personal complaint to overcome these limits.Consequently, if we are qualified then there is no need for the curse. There is no critical need for God to quell our violent opposition. Hence, inability goes beyond our application that we unconditionally must accept the limits in this world and fall on the side of humanism. But inability rises up in the curse and aggressively confronts the relentless opposition in the proper spirit of justified righteousness. 7 "Show the wonder of your great love,you who save by your right hand those who take refuge in you from their foes.8 Keep me as the apple of your eye;hide me in the shadow of your wings
