Spiritual disease affects us eternally. And if we are spiritually sick our whole being is sick. We must let ourselves renew our mind. Our head (mind) must be cleansed by the Lord.
In the spiritual part many have a sick heart so our hearts have to be changed as God did with Joseph and many men in the Bible. God remains the same. And you need to have a healthy and restored church.
