Galatians 5:23

And those who belong to Christ Jesus have crucified the sinful nature together with its passions and appetites. If we live by the Spirit, we must also walk by the Spirit (with personal integrity, godly character, and moral courage-our conduct empowered by the Holy Spirit).

The flesh (mind, will, and emotions) does not retain the wisdom of Christ. Our born-again spirit does through the guidance of the Holy Spirit. We need to question our emotions and not follow them when they lead us into anger, sadness, depression, hopelessness, and more. It takes training and focus to learn to use the Wisdom of the Holy Spirit as our life filter.
