Mark1:1 NIV
[1] “The beginning of the good news about Jesus the Messiah, the Son of God…”

Mark begins his story about Jesus, God’s Son and Messiah with a blunt announcement…

… Not a birth notice in the daily newspaper or even an excited disclosure after an ultrasound scan, “We are pregnant!” but…

Just a bald statement, “The beginning of the Good News,” as if Jesus had just appeared on earth from heaven as a full grown man!

Mark said nothing about His childhood, or even His background and ancestry as a human. Why did he omit all the exciting and miraculous details surrounding His conception and birth?

Mark did not specifically state the purpose of his gospel but, in the divine plan of the Father, it fits in perfectly into the fourfold revelation of Jesus in the four gospels as the king of Israel (according to Matthew), the Servant of Yahweh (according to Mark), the Son of Man (according to Luke), and the Son of God, (according to John).

In keeping with a servant, to Mark  Jesus’ ancestry was irrelevant. Servants are just that, servants, not celebrities. Yet, at the same time, this servant had an ancestry in God clearly prophesied in the Tanach, the Old Testament Scriptures. He was the Father’s divinely appointed Servant, chosen before time to carry out His will, whose character, work, and suffering were predicted centuries before His coming.

Isaiah saw and predicted in four, possibly five “Servant Songs”, called  the Ebed Yahweh, contained in the chapters from 40 to 66 of his prophecies.

Google explains…

“In Isaiah’s prophecies, the “Ebed Yahweh” or “Servant of the Lord” refers to a figure who is both a servant and a chosen one of God, playing a significant role in God’s plan of redemption. This figure is depicted in four distinct poems within the book of Isaiah, each highlighting different aspects of his character and mission. While the identity of the Ebed Yahweh is not explicitly stated, many interpretations identify him as a messianic figure, with some seeing a connection to Jesus Christ.”

“The term “Ebed Yahweh” literally translates to “Servant of the Lord” and appears in Isaiah 42:1-4, 49:1-6, 50:4-9, and 52:13-53:12.”

Appropriately, this Sevant of God needed a forerunner to prepare His way. He would not appear out of nowhere unannounced. Certain details predicted by the prophets, would identify this forerunner so that there would be no mistake in recognising this Servant when He came.

Mark 1:2-4 NIV
[2] “…as it is written in Isaiah the prophet: “I will send my messenger ahead of you, who will prepare your way”— [3] “a voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him.’ ” [4] And so John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins.”

And so John came…out of the wilderness…a wild man…

Mark 1:6 NIV
[6] “John wore clothing made of camel’s hair, with a leather belt around his waist, and he ate locusts and wild honey.”

… with a radical message of repentance, not new for Israel but with a new focus and a new announcement.

Mark 1:7-8 NIV
[7] And this was his message: “After me comes the one more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. [8] I baptize you with water, but he will baptize you with the Holy Spirit.”

Baptism! Israel’s way of drawing a line in the sand…washing off the old, stepping into the new. John’s baptism was new but not new.

Mark 1:5 NIV
[5] “The whole Judean countryside and all the people of Jerusalem went out to him. Confessing their sins, they were baptized by him in the Jordan River.”

What was the meaning of John’s baptism? Over the centuries, the people of Israel had gone through the ritual washing of “baptism”, in the “mikvah”, the pool of water designated to be the place of washing.

Google explains…

“In the Old Testament, a mikvah is a pool of water used for ritual immersion to achieve purification from spiritual or ritual impurity. It’s a place where individuals immerse themselves to become ritually clean, often after experiencing states of impurity due to bodily functions or before engaging in sacred activities. The concept is rooted in the idea of “living waters” or natural bodies of water, though modern mikvahs are often specially constructed pools.”

“A mikvah in the Hebrew Bible is a gathering or collection of water. The word came to refer to a pool of water used for ceremonial cleansing. One who is impure or ceremonially unclean before immersion will be pure or ceremonially clean after immersion in a mikvah. A person would have to be ceremonially clean before entering the temple. Ceremonial cleansing is prescribed in the Bible on a number of occasions: women after childbirth or their monthly cycle and men after sexual discharge (Leviticus 15:19–30) and after contact with a dead body (Numbers 19:18–19). Clothing and utensils could also be cleansed by ritual immersion (Leviticus 11:32). Later, ritual immersion—baptism—became part of a proselyte’s conversion to Judaism.”

Question: What is a mikvah?)

John, then, operating within the culture of Israel, introduced to “mikvah” the concept of repentance for the forgiveness of sins using the Jordan River as his “mikvah”. This was much more than ceremonial cleansing. This was the forerunner of the work of the Servant…cleasing of the heart and conscience through the forgiveness of sin in preparation for immersion in the Holy Spirit.

God has promised, in the terms of the New Covenant…

Jeremiah 31:31-34 NIV
[31] “The days are coming,” declares the Lord, “when I will make a new covenant with the people of Israel and with the people of Judah. [32] It will not be like the covenant I made with their ancestors when I took them by the hand to lead them out of Egypt, because they broke my covenant, though I was a husband to them,” declares the Lord. [33] “This is the covenant I will make with the people of Israel after that time,” declares the Lord. “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people. [34] No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know me, from the least of them to the greatest,” declares the Lord. “For I will forgive their wickedness and will remember their sins no more.”

… and…

Joel 2:28-29 NIV
[28] “And afterward, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions. [29] Even on my servants, both men and women, I will pour out my Spirit in those days.”

The people of Israel had only known ritual cleansing through the sacrifice of animals. The Servant would come with the Good News of heart cleansing through the blood of the Lamb.

Hebrews 9:13-14 NIV
[13] “The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. [14] How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!”

So, Mark shines the light on Jesus as God’s Servant, serving the Father  in His life, His works, and in His death… always at work, fulfilling His Messianic role as predicted in Isaiah’s prophetic songs. His work of salvation from sin, introduced by John the Baptist through his message and the baptism of repentance, would fulfil everything the Old Covenant had promised, ushering in the kingdom of God, the realm of God’s rule restored to earth.
