How did Jesus fulfill the law for believers?

Jesus fulfilled the law on behalf of believers by living a sinless life and obeying all Scriptures' requirements. As stated in Hebrews, it was crucial for Christ to be made like unto His brethren to act as a merciful high priest. He accomplished everything the law required, providing a perfect righteousness that is imputed to those who believe in Him. Thus, through faith, believers are not justified by their works but by Christ’s obedience and sacrifice. This understanding brings profound assurance, knowing that while we are incapable of keeping the law perfectly, Christ has succeeded on our behalf, granting us access to God and eternal life.
