Mark 2:5

When Jesus saw their faith. Our Lord is moved to shew mercy to sinners, by the faith and desires, and prayers of others; for this man was not more helpless in his limbs, than in his soul. From this example, we are taught that in sickness the sacraments and helps of the Church, which are the medicines of the soul, should be called for in the first instance; for Christ first healed the sick man's soul, before he removed his bodily infirmity. We also learn that many diseases originate in sin, and that we are to remove the effect by removing the cause.
