How do we know Christ's righteousness is sufficient?

Christ's righteousness is sufficient because it fulfills the demands of God's justice for mankind. The white fence around the tabernacle illustrates the perfection required to enter into God's presence. Since Jesus is both fully God and fully man, His righteous life and sacrificial death satisfied divine justice completely. Believers are credited with His righteousness, as laid out in 2 Corinthians 5:21, affirming that we are made righteous in Him. This righteousness not only enables access to God but also guarantees our eternal security as we remain in Christ.
