The Apostle Paul felt this.
So I find it to be a law that when I want to do right, evil lies close at hand. For I delight in the law of God, in my inner being, but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin. (Romans 7:21-25)Have you ever stopped where you stood and been reminded of your absolute undeserving character? Have you ever knelt before God and been struck by the near-preposterous nature of the situation? Who are we to approach the throne of a pure, undefiled, holy, righteous and just God? Who are we to possess His grace?
Grace. Have you ever pondered how undeserving you are to receive not just God's saving grace, but even His common grace and blessings? Who are we to be privy to the beauty of a sunset? Who are we to be allowed to awake another day, to share the love of family and friends, to rest in the cool breeze of evening? Who...are...we?
Ah, but that is the wrong question. The question is not, "who are we?" Rather, the question is, "who is Christ?"
There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit. (Romans 8:1-4)
For while we were still weak, at the right time Christ died for the ungodly. For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die—but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation. (Romans 5:6-11)Amazing grace indeed.
