Why is faith essential for righteousness in Christianity?

Faith is crucial because it is the means by which righteousness is attained. Romans 10:9-10 teaches that if one confesses Jesus as Lord and believes in the heart that God raised Him from the dead, they will be saved. This signifies that belief in Christ's atoning sacrifice provides a righteousness that is not based on our works but is a gift from God. As Paul emphasizes, the righteousness that comes through faith is distinct from the righteousness based on the law, which requires perfect obedience. Therefore, faith connects believers to the righteousness of God found in Jesus Christ.
