Matthew 16:23

Colossians 3:2 NIV
Set your minds on things above, not on earthly things.

Philippians 3:19 NIV
Their destiny is destruction, their god is their stomach, and their glory is in their shame. Their mind is set on earthly things.

Romans 8:5-8 NIV
Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. Those who are in the realm of the flesh cannot please God.
