What is said to bring about justification and new birth?

The concept of justification and new birth is central to Christian theology, particularly in the context of salvation. Faith in the blood of Jesus Christ is considered the proper foundation for both justification and new birth because it emphasizes the fundamental belief that Jesus' sacrificial death and atoning blood cleanse believers from sin and establish a right relationship with God.

Justification refers to being declared righteous by God, which occurs through an individual's faith in Christ's redemptive work, particularly His sacrifice on the cross. This understanding is rooted in various scriptural references, such as Romans 5:9, which speaks about being justified by His blood, and Ephesians 1:7, which highlights the redemption we have through His blood.

New birth, or being "born again," is also intrinsically linked to the work of Jesus. Jesus discussed this in John 3:3, indicating that one must be born of the Spirit, which is facilitated by the faith in Christ's redemptive power. This birth into a new life is made possible solely through the sacrificial and redemptive nature of Jesus’ blood, affirming believers' transformation and renewal in their spiritual journey.
