Jesus was going about Teaching, Preaching the Good News of the Kingdom of God and Healing every kind of disease and every kind of sickness among the people.
Teaching the principles of the Word of God instructs or gives direction to the heart about eternal life and how to live an abundant life here on earth.
Preaching the Good News brought hope to the hurting heart with the promise of a better life and salvation (when your spirit is born again).
Healing the heart brings health to the body and the soul (your intellect, will and emotions). Remember that Jesus wants a personal relationship with you and to live with you because Christianity is a living movement and not a dead monument.
JESUS IS THE GREATEST SERVANT OF LOVE!!!
