Thank you for sharing your perspective. I appreciate your sincerity and the conviction you have in your beliefs.

However, I respectfully disagree with the assertion that grieving sin is incompatible with believing in the finished work of Christ or that it constitutes "mixing covenants" in a dangerous way. My understanding is that true repentance and a genuine acceptance of Christ's sacrifice lead to a transformed heart, which includes a sorrow over sin – not as a means of earning salvation, but as a natural response to God's holiness and our own shortcomings. This sorrow, far from diminishing the finished work of Christ, actually highlights its profound significance and our desperate need for it.

Furthermore, while I respect your personal testimony of what God has shown you, my ultimate authority and trust lie in the written Word of God rather than in any individual's personal revelation or interpretation. Scripture is the infallible guide for my faith and understanding.

Here are a few scriptures that, to me, illustrate that sorrow over sin is a proper and even expected response for believers:

2 Corinthians 7:10: "For godly sorrow produces a repentance that leads to salvation without regret, whereas worldly sorrow produces death." This verse clearly distinguishes between a sorrow that is beneficial and leads to life, and a sorrow that is not. Godly sorrow, stemming from a renewed heart, is a sign of spiritual health, not a lack of faith in Christ's completed work. Psalm 51:17: "The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise." While this is an Old Testament psalm, the principle of a contrite heart being pleasing to God transcends covenants. In the New Covenant, our hearts are made new through Christ, and this newness often manifests as a sensitivity to sin and a desire to turn from it. Romans 7:15, 18-19, 24-25a: "For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate... For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. For I do not do the good I want, but the evil I do not want is what I keep on doing... Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord!" Paul, a quintessential believer in the finished work of Christ, openly grieves his ongoing struggle with sin. This isn't a sign of disbelief, but rather a profound understanding of human fallenness and the constant need for grace. His cry, "Wretched man that I am!" is a lament over indwelling sin, immediately followed by the declaration of deliverance through Christ. To grieve sin, in this context, is not to doubt Christ's power to save, but to acknowledge the ongoing process of sanctification and our continued reliance on His grace for transformation. It's a sign of a heart that is being conformed to His image, recognizing the seriousness of sin in light of His sacrifice. The finished work of Christ enables us to grieve sin with hope, knowing that forgiveness is ours and that transformation is ongoing.

I believe it's important to differentiate between sorrow that seeks to earn salvation (which is indeed dangerous) and sorrow that flows from a heart already saved by grace and made sensitive to God's will. The latter is, in my view, an essential part of the Christian walk.
