How does the believer’s nature affect their relationship with sin?

Upon conversion, believers receive a new spiritual nature, as stated in Psalm 32:2, described as one in which there is 'no guile.' This new nature enables believers to see the sinfulness of their former selves. Nevertheless, they are also aware of their ongoing struggles with sin. The presence of an old sinful nature persists, leading to an intrinsic conflict that is articulated by Paul in Romans 7. This duality forces believers to rely on God's grace for continual forgiveness while striving to live in a manner that reflects their new identity in Christ.
