How do we know that Jesus Christ is the law keeper?

Jesus Christ is described in the Scriptures as the only one who has kept the law perfectly, fulfilling all its requirements in every detail. As a man, He faced the same temptations and weaknesses as we do, yet He did so without sin. In Hebrews 4:15, we are reminded that He was tempted in all things as we are, yet without sin. This unique ability to keep the law grants Him the status of the law keeper, the one through whom we can understand righteousness. By being in Christ, believers are seen as fulfilling the law's demands not because of their own merit but through His righteousness.
