According to Hebrews 5, throughout his life, Jesus learned obedience through increasing difficulty with the result that he would be prepared to take this final step of obedience by submitting to the Father’s will in the Garden of Gethsemane.
It’s this real fight of faith and pinnacle of submission that we see in Jesus, which not only secures our salvation, but provides the ultimate prototype for all Christian obedience. That’s because the Christian life is all about saying “no” to ourselves, or in the words of Christ, denying oneself, and instead, saying “yes” to what God says. This will take faith and being strengthened through dependent prayer. We see nothing different in the Son of God’s pinnacle of obedience in that he denied himself, even his very life, though he never sinned against the Father and deserved full worship from every person who came across his path. So if anyone had reason to justify disobeying the Father’s will, it was Jesus Christ, but he was more determined to glorify God than protecting and promoting himself.
