How do we know Christ's obedience was perfect?

The perfection of Christ's obedience is evidenced in His unwavering love for God, expressed in His willing sacrifice. In John 15:13, Jesus emphasizes that there is no greater love than to lay down one's life for friends. He demonstrated this love by perfectly obeying the law, something that no one else could achieve. God's holiness requires absolute perfection, and only Christ, as the sinless Son of God, could stand in our place and fulfill this requirement. His complete submission to the Father exemplifies His divine character and righteousness.
