What does justification mean in the Bible?

In theological terms, justification refers to God's declaration that a sinner is righteous due to faith in Jesus Christ. This concept is primarily drawn from Romans 4:25, which asserts that Christ was raised for our justification. Through His sacrificial death, Jesus paid the penalty for the sins of His people, effectively making their sins not exist in the eyes of God. Justification is not merely a legal standing; it is transformative, marking believers as truly righteous and accepted by God. This profound doctrine underscores the necessity of faith, as it is through faith that individuals are justified, removing the burden of their sin and establishing a new relationship with God.
