Confusion abounds: Did Jesus nullify the Law?

No; the point is this, Jesus is the END OF THE LAW CONCERNING “RIGHTEOUSNESS” (Romans 10:4); that is, because of what Jesus did for you and me at the Cross through His sinless perfection, we no longer strive through human effort to be worthy to the Father in a vain attempt to earn our own salvation via law keeping (Galatians 2:16) i.e. self-righteousness but Jesus kept the Law in sinless perfection and gave Himself as an atoning sacrifice for our sin and by covenant promise, the Father agrees to impute the perfection – righteousness of Jesus over your life by faith in Jesus as your Lord and you are therefore declared “not guilty” when you trust-believe that Jesus is Lord and that Jesus died to pay your sin-debt owed the Father (Hebrews 8:12; 2 Corinthians 5:21). The Father accepts the perfection – the sinless sacrifice of Jesus, the spotless Lamb of God, as payment for your sin-debt and NOTHING else will supplement or supplant Jesus as our substitutionary death for our sin (John 14:6)…NO LAW…NO WORK…NO RELIGION!

Once you are redeemed-saved-justified-family by faith in Jesus and covenant relationship is guaranteed by the Gift of the indwelling Holy Spirit (Ephesians 1:13-14) you are then led by the Spirit in the daily process of sanctification where the Spirit begins a good work in you and through you via the conscience; you are methodically led in obedience to the Father’s will for your life via the moral law of conscience written upon your heart and arbitrated by the Spirit; you no longer strive in vain after the written law – self-righteousness but the intent of the law is methodically fulfilled by the Spirit’s work through you as you have been forgiven by grace (unmerited favor from the Father) through faith-trusting in Jesus as your Lord and you naturally seek obedience because you love God and you’re now HIS child, His family, forever (John 3; Galatians 5:16).
