Mark 1: Gospel 1st step: Repentance for our sins

Mark 1:1-11
John came as Isaiah 40:3 said to be messenger ahead of Jesus Christ.
'Prepare the way for the Lord, make straight paths for him.'
John preaching a baptism of repentance for the forgiveness of sins.
John baptize you with water, but He will baptize you with the Holy Spirit.
When Jesus was baptized by John, a voice came from heaven:"You are my son, whom I love; with you I am well pleased."
This is the shortest of the Gospels and probably the first to be written. Mark wrote the Gospel in Rome, setting down Jesus' story as he had heard it directly from the apostle Peter.
Mark, who was the interpreter of Peter, wrote down accurately all that he remembered, whether of sayings or doings of Christ, but not in order.  For he was neither a hearer nor companion of the Lord.
Mark is the Latin name, his mother had a house in Jerusalem where Jesus followers met in the days of the early church. He was cousin to Paul's companion, Barnabas. Peter, whose companion he became, loved him as his own son(1 Peter 5:13)
Mark shows us Jesus in action, convincing us by the things he does that his claim to be the Son of God is true.
Why?
Water is a symbol. It can clean only the outside. God's Holy Spirit can cleanse a person from within.
John has only the simplest of food and rough clothing. He was certainly recognized instantly as a prophet. People flocked from far and wide to hear him, probably gathering beside the Jordan near Jericho, close to the place where Joshua had led the Israelite into their promised land so many centuries before.
John came consist with the words of Isaiah, his living style like a prophet and he preach the words of repentance, prepare the way of the Jesus Christ.
John's word proves that Jesus Christ is the Son of God.
John preach the baptism of repentance for the forgiveness of sins, Jesus gives not only repentance messages, but also the gospel of everlasting life. Jesus gives us the hope, before get the everlasting life, it is a necessary procedure to repentant for our sins.
Repent for our sins, invite Jesus as our savior, baptism to show our action.
How?
Goal of my life is 1)Preach the message of repentance for our sins and 2)Lead them accept Jesus as our savior, 3)Baptism them with Holy Spirit through Christ.
It is clear of my goal in my life.
