If we are spiritually ill, our bodies and minds also become sick. This is why regular prayer and times of silent contemplation are necessary parts of our daily lives. Periodically, we must also take extra measures of self-examination and learning, that we might be ever-perfected in the grace of the infinite and perfect God.
