Read: Romans 8
“An unsaved person, who is ruled by his sinful nature, sets his mind on the things of the flesh. A saved person, because of the work of the Holy Spirit within him, sets his mind on the things of the Spirit. This is an important self-examination verse. Indeed, this is an important self-examination section because Paul is describing the difference between a person who is not saved – that is still in the flesh – and a person who is saved - who is being changed by the Holy Spirit.”
