1 Corinthians 2:14 ESV

The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned.

The more fleshly desires (natural person) you can overcome by reading and hearing and studying Gods word and praying as much a possible daily the more things of the Spirit of God you will see and understand because of renewed mind by the Holy Spirit in you.
