“On the one hand, God is holy and just and cannot tolerate or live with or bless evil. On the other hand, God is loving and faithful and cannot tolerate the loss of people he has committed himself to. This is a tremendous, seemingly irresolvable tension…It is oly on the cross that we can understand how God is able to resolve the tension…Without the gospel of Christ crucified, we will always either complacently give in to sin (because of the unconditionality of his promises), or live under a burden of guilt and fear (because of their conditionality). The cross is where we find the tension resolved, so we are to live forgiven, obedient lives despite also living sinful, disobedient lives. The cross is the place where we find the freedom to accept ourselves, without being proud, and to challenge ourselves without being crushed.” Tim Keller

I agree with this and want to make a point about the struggle we have with our weaknesses. The Psalmist says" I was overcome by trouble and sorrow" The Psalmist depicts our inward sorrows and our distresses due to out trials as a weight that is too heavy for us to carry. We must understand that sin is not only the destructive part that Christ must atone for but because we carry around this body of sin...or the flesh we still have tendency to react to our trials in a cursed way. Even tho the curse has been taken care of in Christ , yet we still carry around this body of death...our human weakness combined with the nature of sin. We will feel the weight of this corruption until we go to heaven where there will be no more sorrow, no more tears etc.
We experience the power of the curse even tho we have been freed from it. The power of the curse is the anger we experience from the trial. We have been given a moral compass that rises up when we sin or have been sinned against. The cross is not just about personal atonement but it is the cause of the success of Gods universal government to redeem a people to Himself by paying the purchase price for His people who have suffered on this earth. We go from being enemies of Christ to enjoying a full substitute Who has gone out before us and done the work necessary for us to be accepted by God who has become our Father. The purchase price for our suffering is not according to the level of suffering we go through but its according to the price of His blood that He poured out for us on the cross. He reacts to our suffering on a level of justified anger- (whos purpose is for our defense and not a hot reaction).... that is far beyond our anger that we experience in the curse. When we live in this realization His anger consumes our anger.
