How do we know the doctrine of Christ's obedience is true?

The doctrine of Christ's obedience is rooted in the biblical assertion that he came not to abolish the law but to fulfill it (Matthew 5:17). Throughout His life, Jesus was obedient to the will of the Father, exemplified in His declaration in Hebrews 10:7, where He expresses His purpose: 'Lo, I come to do Thy will, O God.' This obedience is essential because only through His perfect life could He serve as an acceptable sacrifice for our sins. Furthermore, Isaiah 42:1 describes the righteous servant whom God would uphold, showing that Jesus’ mission was prophesied and integral to God’s plan for salvation.
