What is more, I consider everything a loss because of the surpassing worth of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which is through faith in Christ—the righteousness that comes from God on the basis of faith.
Philippians 3:8‭-‬9 NIV

I believe we all reach a point in our walk with Christ where we see the meaningless value of things we once held dear: the pursuit of wealth & material gain, (self-perceived) position & power, sex, etc. As we transition from a carnal to a spiritual value set, we can know the peace of Christ that passes all understanding.

Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them. For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world. The world and its desires pass away, but whoever does the will of God lives forever.
1 John 2:15‭-‬17 NIV

And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Philippians 4:7 NIV
