In this passage, Jesus is trying to teach the Pharisees and Sadducees that they can’t rely on their heritage or their forefather’s faith to obtain righteousness. But true righteousness can only come from Jesus as He is the only one who could and did live a sinless life out of obedience to God and out of love for us. Romans 5:8 says “but God shows his love for us in that while we were still sinners, Christ died for us.” Romans 6:23 says “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” Jesus never asks for us to come to Him perfect but as we grow in our faith we should see growth in our obedience to His commands as He changes our hearts.
