What does the Bible say about the believer's struggle with sin?

The Scripture reflects a realistic view of the believer's struggle with sin, acknowledging that although they are positionally sanctified in Christ, the remnants of sin remain in their lives. Believers experience inner conflict between their new identity in Christ and the persisting sinful nature. Romans 7 captures the essence of this struggle as Paul expresses his wretchedness in dealing with sin, affirming that it is through Christ alone that he finds deliverance. This struggle emphasizes the need for continual dependence on God's grace, as believers are called to grow in their relationship with Him and seek His strength to resist sin. The presence of this struggle can also serve as a source of assurance for believers that they are indeed children of God who earnestly desire to walk in holiness.
