Why is understanding indwelling sin important for Christians?

For Christians, understanding the concept of indwelling sin is crucial as it highlights the ongoing reality of their spiritual battle. Newton argues that a proper acknowledgment of this sin fosters humility and drives believers toward a deeper appreciation of God's grace. When Christians are made conscious of their fallen nature and their continuous struggle against sin, it leads to a more profound reliance on Christ as their Savior. They learn to appreciate the depth of their need for daily mercy and the continual need for the Spirit's empowerment, thus cultivating a more vibrant faith and a life characterized by humble gratitude.
