What is the significance of the struggle with sin for believers?

For believers, the struggle with sin is a significant part of their spiritual experience. In Romans 7:14-25, Paul expresses the internal conflict between his sinful nature and his desire to obey God. This struggle is an indication that believers possess a new nature created in Christ, which opposes the old sinful nature. The very fact that believers mourn their sin and strive toward holiness indicates the presence of the Holy Spirit within them. Understanding this struggle emphasizes the necessity of relying on God's grace daily and acknowledging that we are dependent on Christ’s righteousness rather than our own. It reminds believers of the ultimate victory they have in Christ over sin and the ongoing process of sanctification in their lives.
