"For to be carnally minded is death; but to be spiritually minded is life and peace. Romans 8:6"
The natural/carnal mindset ends in death or is short-lived. To be carnally minded or to have a natural mindset is to be led by the five natural senses of the body, that is, the sense of sight, smell, hearing, taste, and touch/feel.
These are the children of God who are concerned about only what will gratify the body. In other words, they are only concerned about what to eat, wear, and live by whatever they see, hear, or feel: they are not concerned about their spiritual needs.
On the other hand, those who are spiritually minded or have the heavenly mindset have prioritized their spiritual needs above everything else: they live by the Word of God.
These are God's children who give priority to the study of the Holy Scriptures, prayer, fellowship, righteousness, brotherly love, faith, hope, worship, and praise; these activities can only produce life and peace.
Hallelujah! Dearly beloved, have you developed your spiritual mindset? The choice is yours!
