"We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete." - 2 Corinthians 10:5-6 ESV
"But overhearing what they said, Jesus said to the ruler of the synagogue, 'Do not fear, only believe.' " - Mark 5:36 ESV
Our obedience is complete when we 'only believe'.
"When Jesus had received the sour wine, he said, 'It is finished,' and he bowed his head and gave up his spirit." - John 19:30 ESV
His complete obedience is put on our account when we believe. Believing in Jesus is complete obedience. Then a desire to 'punish' or 'revenge' disobedience is placed in our minds. We don't want to go backwards or live in faithlessness anymore. We want to revenge our former faithlessness with present and future faith.
We can't punish our disobedience unless our obedience is complete. Jesus is the only place we will ever find a complete obedience. We will never find it in our self. If that is where we are looking then we will be disappointed in our continual striving for perfection.
"Looking unto Jesus the author and finisher of our faith..." - Hebrews 12:2a KJV
