Jesus is the cure to all our sins, in fact, his death paid for it (past,present,future) that's why we have "grace" now, and he was pierced on the wrist altogether with all the symptoms (feelings of guilt, anxiety, condemnation, etc.) of it [sin] - and not the Law. Measuring up to it [law] will always make us feel not good enough and worn out, always tired and feeling empty afterwards, feeling inadequate and always undeserving of grace.
But if we keep focus on Christ and his Kingdom (Colossians 3:2), the less the law is being magnified and the more he becomes magnified as the center of our why's and endeavors, all the more we realize that by being soaked in Christ, the things written up in the Law is being done and fulfilled in us by Christ himself (Romans 8:2) and only Christ who is in us! (Philippians 2:13) We don't make the Law the savior of our lives, Jesus is! The Law is the manual, but Christ is the Savior!
The Law inspires us all the more to move towards Christ, not to take the place of Christ. Don't make a band-aid out of the Law, it's not the measurement of how good we are, of how much we've done, how great of a person we are and how righteous we are. Christ, who is in us, is the measure of our whole being. We were redeemed at a high Cost.
Thus, making us purchased in Christ's identity (John 1:12).
Regardless of our efforts in meeting up with the Law, without Christ as the center, everything is nothing but vanity. We can never cure ourselves on our own, what more then if we keep away from the Cure himself? Jesus is our righteousness, not ourselves, not even if we double our efforts in fitting up with the law! Therefore by all means, without Jesus we are not righteous!(2 Corinthians 5:21)
The sole reason why he calls the unqualified since he qualifies them all by being in them! We are being made righteous in Christ, therefore when found in him, all are forgiven, loved, blessed and favored and highly redeemed! Remember, grace is never earned - it is freely given - to those in Christ! So what do we do? We remain in Christ and if not yet, we come to realize that we need a Savior. Separated from him (John 15), we can never earn grace nor even produce anything but vain efforts.
God blesses us only through Christ, and only through Christ can we gain everything we need to survive (Ps. 23). And to us, who are in him, we have all access to God's unchanging grace! Because only then if we have Jesus in us can we claim the Truth (John14:6) that we are free (John 8:32), loved, blessed, favored, protected, anointed and most of all, redeemed (Ephesians 1:7) from the debt of sin!
Now, we don't need a band-aid to cure ourselves, we need the Cure, who is Christ. :)
