How does Christ fulfill the requirements of righteousness?

In fulfilling the law, Christ lived a sinless life and demonstrated perfect obedience, becoming the embodiment of righteousness. Isaiah 42:1 exclaims that God delights in Him because of this righteousness. Through His death and resurrection, He not only satisfied God's justice but also provides righteousness to all who believe in Him. This is crucial for our salvation because it indicates that we are made righteous in God's sight through our faith in Christ, not through our own actions.
