None of us is a sinner. Noone who knows Christ, noone for whom Christ shed His precious blood is a sinner. In Christ we are made new, we are renewed through Christ's healing power, so that even when we continue to sin, we are not sinners, because every single sin we commit has already been covered in Christ's blood. There is nothing so powerful that it can separate us from God's love. "And if any man sin, we have an advocate with the Father, Jesus Christ the righteous" 1 John 2:1. "There is therefore now no condemnation to them that are in Christ Jesus." Romans 8:1. This then is God's comfort for us, that we cannot ever turn away from Him. If we believe on Him, even if we feel nothing, even if we feel completely alone and as if He does not love us, His love remains steadfast forever, and His mercy continues ever on. "So when the devil throws your sins in your face and tells you that you deserve death and hell, tell him this: I admit I deserve death and hell, what of it? For I know of one who suffered and made satisfaction on my behalf. His name is Jesus Christ, the Son of God, and where He is, there shall I be also"-Martin Luther. No matter how we feel, we cannot separate ourselves from God's love "For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord."-Romans 8:38-39. No sin we commit can separate us from that Love. Christ's sacrifice on Calvary paid for our sins once and for all. We need no other sacrifice, and we need no other help. Christ's sacrifice is eternal, and he intercedes now at the Right Hand of His Father for all the sins of his people. It is for this reason that David was able to say "Blessed is the man whose sin the LORD does not count against him and in whose spirit is no deceit" because when we confess our sins to God, we are forgiven, and our souls are as if we had never sinned at all. So when we feel the weight of our sins, and we confess them to God, it is really a doubting of the efficacy of Christ's sacrifice if we continue to bear the weight. "Then I acknowledged my sin to You and did not cover up my iniquity. I said, "I will confess my transgressions to the LORD" and You forgave the guilt of my sin"-Psalm 32:5
It is for this reason that we need not doubt our faith when we sin grievously. There is no sin so great that Christ's blood has not covered it. There is no reason to dwell on our guilt and sin. There is no reason to attempt to "make up for it" in some deed or work. We need only plead the Cross, and lift up our sins unto God, and turn away from those sins in repentance, and we need fear nothing, for He is with us. We need only pray "Create in me a clean heart, O God; and renew a right spirit within me" ( Psalm 51) and we are renewed. For each of us is at the same time a great sinner and not a sinner at all, as all of God's people are renewed through His sacrifice of His Son Christ on the cross, and we are made whole in His blood, and it is as if we had never sinned at all.
"Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need."-Hebrews 4:16
"What shall we then say to these things? If God be for us, who can be against us? He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Who shall lay any thing to the charge of God's elect? It is God that justifieth. Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us."-Romans 8:31-34
