“For to be carnally minded is death, but to be spiritually minded is life and peace.”
A carnal minded person is someone who is focused on the things of this world. Now for those that have not accepted Jesus Christ as their savior this type of thinking is not abnormal because they do not know the things of God and are unaware of the peace and joy that can be found by accepting Jesus as their savior. Their lives rage with uncertainty, they look in all the wrong places to find a way to calm the storm of life they live.
Now the ones that are Christians(those who have accepted Christ as their savior) can also be carnally minded seeking the things of this world (money, power, fame, etc.). They are saved by grace and will not experience an eternal hell, but they will face a life away from God. You see the carnally minded face death which means separation from God because the carnally minded are not seeking God but if we seek God and the things of God we will find peace. Psalm 29:11 "The Lord gives strength to his people; the Lord blesses his people with peace.
We must remember to have peace in our lives or peace in our minds then we must seek after the things of God because only He can provide the peace we seek.
