During his three-year ministry, Christ Jesus overcame innumerable forms of evil, healing people of all kinds of maladies, freeing them from all kinds of sin, even overcoming death. Jesus' pure, spiritual love for God and man, as well as his understanding of God's omnipotence, enabled him to bless people in ways they had never before thought possible.
His countless and unparalleled healings roused people's thinking, forcing many to take notice and to consider whether Christ Jesus was indeed the Messiah, as he himself declared he was. Jesus' works verified his teachings, including the essential thrust of those teachings: the need for all of us to put off sin in order to demonstrate the harmony of true being.
For humanity to be freed from suffering, it must also be freed from the iniquity inherent in mortal mind, or the carnal mind, which is the source of the suffering. Not every instance of disease or other suffering is the direct result of sin; often it's simply the outward effect of fear, stemming from an ignorance of God and how He has created man. But sin of every sort does inevitably produce suffering, until the sin is destroyed. Hence the infinitely tender purpose and pure love manifested in Jesus' coming, the design of which was to lead humanity to full salvation and peace.
