…how God anointed Jesus of Nazareth with the Holy Spirit and power, and how he went around doing good and healing all who were under the power of the devil, because God was with him.
In the Old Testament, the blood of sacrifice covered the sins of the people, and they were forgiven. When Jesus came, He cleansed the sin from within us by changing man’s sinful heart (Ezekial 36: 26 I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh.)
In the Old Testament Israel followed God because of the visual , physical manifestations He showed them. Now, we follow God because His Spirit is within us, teaching, leading and guiding us in our Christian lives.
