How does imputation relate to our justification in Christ?

The concept of imputation is pivotal to understanding justification in Christ. When one’s sins are imputed to Christ, it means that He bore the penalty for those sins, effectively canceling the debt owed to God. Conversely, His righteousness is imputed to believers, meaning that they are declared righteous in God's sight. This dynamic is expressed in 2 Corinthians 5:21, where Christ becomes sin for us, and in return, we are made the righteousness of God in Him. Justification thus stands as a legal declaration from God, based solely on Christ's finished work and not contingent on human merit or effort.
