Mark recorded nothing of Jesus’ birth and early years. Mark was concerned to present Jesus as a man of action. An event is completed and Mark notes that immediately another event followed. Mark presented Jesus’ acts, messages, and suffering in light of the Old Testament.
(1) In Mark 1:2-3, Mark employed Isa 40:3 and Mal 3:1 to validate John the Baptist as Jesus’ forerunner. In Mark’s mindset, “the beginning of the gospel of Jesus Christ, the Son of God” (Mark 1:1), necessitated understanding Jesus in light of God’s revelation before Jesus’ birth. Mark and the other Evangelists saw in the words of the prophets a launch pad for describing the life, death, and resurrection of Jesus (Matt 3:1-6//Mark 1:2-6//Luke 3:1-6//John 1:19-23). In Isaiah 1-39, the prophet repeatedly confronted Israel for her sin, urging her to trust the Lord for deliverance. Beginning in Isaiah 40, the prophet proclaimed words of hope. Isaiah announced the day when the Lord would send a forerunner to prepare the people for the day of God’s redeeming power, when He would intervene for His people. Malachi also prophesied that the Lord would send a messenger to prepare the people for the time when God would intervene on behalf of His chosen ones (Mal 3:1). John’s ministry was widely successful. Mark wrote that crowds came from throughout Judea and Jerusalem to be baptized by John. They heard John preach that all must repent and await the day when One more powerful than him would come and baptize the people with the Holy Spirit (Mark 1:4-8).
(2) In Mark 1:11, Mark described the Spirit coming upon Jesus in accord with expectations of the Messiah. The Evangelists portrayed Jesus’ baptism as the inaugural event of the Lord’s public ministry (Matt 3:13-17//Mark 1:9-11//Luke 3:21-22//John 1:29-34). The Spirit of the Lord led Moses (Num 11:16-30), Saul (1 Sam 10:10), and David (1 Sam 16:13; Ps 2:2; 51:11) in their positions of leadership. Isaiah predicted that the Lord’s deliverer would be anointed by the Spirit (Isa 11:2; 42:1, 7; 61:1-2). Mark wrote that the moment Jesus came out of the baptismal waters, the heavens were torn open and the Spirit descended upon Jesus.
(3) In Mark 1:40-45, Jesus cleansed a leper in violation and fulfillment of Leviticus 13-14. Moses established a detailed protocol for how Israel should deal with skin diseases. The priests investigated skin irritations for signs of infection and quarantined those having a disease that could spread. When the disease was healed, the priest would lead the cleansed person in a ceremony so all would know that the person was whole and ready to commune again with the community (Lev 14:1-9). The ceremony required the cleansed person to bring animals for sacrifice and restitution before the Lord and priests (Lev 14:21-32). When a man with a serious skin disease came to Jesus and begged the Lord to heal him, Jesus was moved with compassion (Mark 1:41). In touching the man, Jesus set aside the priestly ritual of Leviticus 13. By His own power, Jesus healed the man instantly. No process or procedure was needed. But Jesus upheld Lev 14:1-32, commanding the man to quietly fulfill the law by giving the priest the offering for cleansing (Mark 1:43-44). Jesus told the man to do this as a testimony to what Jesus had done for him.

Mark 2-3
These chapters of Mark’s Gospel record Jesus’ early ministry in Galilee and roughly parallel events recorded in Matthew 4, 8-9, and Luke 4-6. In Mark 2-3 the author emphasizes Jesus’ unparalleled authority in action. For Mark, Jesus stood supreme as the One who had the authority to forgive sins, the freedom to eat with the unclean, and the right to interpret the Sabbath in light of His entrance into the world. In short, Jesus was not only proclaiming the kingdom of God in His sermons, He was also inaugurating it in His actions. Even Jesus’ mother and brothers needed to align themselves with the time of His coming. Mark wove Jesus’ messages and miracles with their Old Testament precedents to portray Jesus’ supremacy in Scripture’s storyline.
(1) In Mark 2:13-17, Jesus ate with those considered unclean by the standards set forth in the law. In Leviticus 11, Moses detailed the various animals that were unclean and to be avoided by those in the community. Moses repeated many of these stipulations in Deut 14:3-20. In Deut 14:21, Moses stated that the people of Israel were allowed to give unclean foods to resident aliens among them or sell those foods to foreigners but said, “You are a holy people belonging to the LORD your God.” Laws detailing unclean food influenced the Pharisees’ social habits. By dining with tax collectors and sinners, Jesus inverted their paradigm and established a new way of thinking about holiness. Sanctification was now to be expressed by loving benevolence to sinners. Jesus said, “Those who are well don’t need a doctor, but the sick do need one. I didn’t come to call the righteous, but sinners” (Mark 2:17).
(2) In Mark 2:18-22, Jesus’ statements about fasting focused Israel’s patterns of religion in light of His teaching and ministry. The Old Testament required fasting only on the Day of Atonement (Leviticus 16), but John’s disciples and the Pharisees fasted more regularly, distinguishing themselves from Jesus and His disciples (Matt 9:14-17//Mark 2:18-22//Luke 5:33-39). When crowds noticed the varying patterns of religion, they approached Jesus asking why He did not follow the same traditions as John and the Pharisees. Jesus answered that His coming in the flesh demanded that all honor Him over and above contemporary signs of piety. Jesus retorted that His message was not an appendage to Judaism, like a new patch on an old garment, or new wine into old skins. His teaching was the new wine and could only be appreciated by fresh wineskins (Mark 2:22). New patterns of piety were in order and only those that centered on Him were to be followed.
(3) In Mark 2:25-26, Jesus justified His disciples’ eating on the Sabbath by citing the event when David and his men ate consecrated bread from the high priest. When David was on the run from Saul, he came to the priest at Nob and asked for food that he and his men might eat. The priest told David, “There is no ordinary bread on hand. However, there is consecrated bread, but the young men may eat it only if they have kept themselves from women” (1 Sam 21:4). David assured the priest that he and his men were pure. The priest gave David and his men the Bread of the Presence and they ate it (1 Sam 21:6; Exod 25:30; Lev 24:5-9). One Sabbath day, Jesus was going through the grain fields with His disciples and the Pharisees complained when the disciples began to pick grain and eat (Matt 12:1-8//Mark 2:23-28//Luke 6:1-5). Jesus asked them, “Have you never read what David and those who were with him did when he was in need and hungry?” (Mark 2:25). Jesus concluded His argument with the Pharisees by stating His own supremacy over all of salvation history. “The Sabbath was made for man and not man for the Sabbath. Therefore the Son of Man is Lord even of the Sabbath” (Mark 2:27-28).
