Come follow me; Teaching with authority

Mark 1:12-28
Jesus was sent out by Spirit into desert and tempted by Satan 40 days.
Good News: The time has come, the kingdom of God is near. Repent and believe the good news.
Come follow me! At once, Simon and Andrew follow Jesus, without delay, James and John left their father and followed Jesus.
What is this? A new teaching and with authority! He even gives orders to evil spirits and they obey him.
Galilee:
The region lay to the west of Lake Galiee. In Christ's day it was prosperous and densely populated.
Most of the apostles came fro the towns around the lake-shore, which enjoyed a sub-tropical climate. Capernaum was Jesus' base. Tiberias, 16km/10miles away, was a spa town famous for its hot baths. Many of the sick people Jesus healed would have coe to the area for the mineral waters at Tiberias. On the hill behind the town was Herod's splendid summer palace.
In Jesus' day, palms, olives figs and vines grew on the hillsides around the lake. And the little towns and villages on its western shore were thriving center of industry: fish pickled for export; boat building; dye-working; potteries. John the Baptist lived an ascetic life in the desert. By contrast, Jesus chose to be in the thick of things, in Galilee, one of the busiest, most cosmopolitan regions of Palestine.
Why?
Jesus accepted temptation by the leading of Spirit, so as we has temptation in this world. Jesus conquered the test of food, honor and wealth. All of these Jesus is conquered.
 Preach the good news- the kingdom of God is near, repent and believe in Jesus. This is what I should preach to this world also.
Follow Jesus at once, without delay, what I am concerning about? the food? the honor and the money?
Reading the Bible and preach word of the Lord need the authority of God, without Spirit the teaching without authority.
How?
Come with Jesus, He is the son of God, follow the truth at once. Don't read Bible as book, it is a life book concerning everyone.
If I am preaching in church, do I have the authority to teach words of God?
Preach good news among people instead of in desert, do it like Jesus. We need to conquer this world, conquer the testimony of Satan.
