Can we lose our justification through sin?

The nature of justification assures believers that their standing before God is permanent and unchangeable, regardless of their sin. Romans 8:1 states, 'There is therefore now no condemnation for those who are in Christ Jesus.' This security stems from Christ's atoning work, which completely satisfies the justice of God for all the sins of those who believe. While believers may still struggle with sin, their justification is not dependent on their performance but rather on Christ’s righteousness applied to them. As Paul argues in Galatians 2:17, seeking justification through the law after being justified by faith leads to confusion but does not change the reality of one's justified state.
