“Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires.” Romans 8:5
We have a choice in the way we live our lives. The first is to follow our human nature; Paul states that those who choose this way of living set their mind and heart on what their sinful nature desires. The other way to live is to place ourselves under the control of the Spirit; our focus then is on the things that interest God’s Spirit.
The way we live determines how we think about things. It has been said that people do not think themselves into the way they act but act themselves into the way they think.
