An encounter with Jesus Christ that translates to New Birth and Salvation through Faith in Christ only affects your spirit (1Cor6:17, Romans 8:15-17)
Transformation and Renewing of your mind is the name that is given to the salvation of the soul (Romans 12:2)
Renewing your mind simply means embracing who you are in Christ and what you have in Christ as a way of life that affects the way you think; the way you speak and the things you do through the Word of God and the guidance of the Holy Spirit.
Knowledge of God's word without application is unfruitful. (James 1:21-22)
