Grievous Sin After New Creation in Christ Forgiveness
This truth addresses the heart of every believer who has struggled with the weight of sin after coming to faith in Christ. Paul writes in Romans 8:28 that "we know that for those who love God all things work together for good," which includes the assurance that even in our sin, God is working to bring about our sanctification and ultimate glorification. The doctrine of perseverance of the saints, a cornerstone of Reformed theology, teaches that those who are truly in Christ will persevere to the end, despite their struggles with sin.
The gospel connection to this truth is that Christ's sacrifice on the cross is sufficient to cover all our sins, past, present, and future, and that His righteousness is imputed to us, so we stand before God justified and forgiven. A common misconception is that becoming a new creation in Christ means we will no longer sin, but Scripture teaches that while we are new creations, we still live in a body of flesh that is prone to sin.
The pastoral perspective on this truth is one of hope and comfort, reminding believers that while sin is serious and has consequences, it does not define our identity in Christ. Rather, our identity as forgiven and redeemed children of God defines how we approach our sin - with repentance, faith, and a pursuit of holiness, knowing that God is working in us to will and to work for His good pleasure, as Philippians 2:13 teaches, and this gives us assurance of forgiveness and perseverance.
