What did Jesus do for 40 days?
BREAKDOWN
The Bible describes two significant periods of forty days in the life of Jesus, both crucial to understanding his ministry and identity. The most prominent instance occurred immediately after his baptism by John and before the commencement of his public ministry, as recorded in the Synoptic Gospels (Matthew 4:1-11; Mark 1:12-13; Luke 4:1-13). During this time, Jesus was led by the Spirit into the wilderness, where he fasted for forty days and forty nights. This period was not merely one of physical deprivation but a profound spiritual trial, during which he was tempted by Satan. The temptations presented a challenge to Jesus' identity as the Son of God and his understanding of the Messiah's role. Satan tempted him to turn stones into bread (a test of physical need and misuse of divine power), to throw himself from the temple (a test of trust in God, seeking sensationalism), and to worship Satan in exchange for earthly kingdoms (a test of allegiance and the nature of his kingship). Jesus unequivocally resisted each temptation by quoting Scripture, demonstrating his perfect obedience and reliance on God's Word, and establishing the true nature of his kingdom as spiritual rather than worldly power. This wilderness experience served as a period of intense preparation and confirmation of his divine mission. It mirrored Israel's forty years in the wilderness, but unlike Israel, Jesus emerged victorious, setting an example of perfect submission to God's will. He demonstrated that true strength comes from spiritual discipline and adherence to God's commands. The ultimate triumph over Satan in the wilderness underscored his authority over evil, a foundational aspect of his subsequent ministry of healing, deliverance, and teaching. Following this period, Jesus returned to Galilee in the power of the Spirit, ready to proclaim the good news of the Kingdom of God. The forty days of fasting and temptation solidified his resolve and perfectly prepared him for the monumental task ahead.

SCRIPTURE REFERENCES
Matthew 4:1-11
Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. When he had fasted forty days and forty nights, he was hungry afterward. The tempter came and said to him, “If you are the Son of God, command that these stones become bread.” But he answered, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.’” Then the devil took him into the holy city. He set him on the pinnacle of the temple, and said to him, “If you are the Son of God, throw yourself down, for it is written, ‘He will give his angels charge concerning you;’ and, ‘On their hands they will bear you up, so that you don’t dash your foot against a stone.’” Jesus said to him, “Again, it is written, ‘You shall not test the Lord your God.’” Again, the devil took him to an exceedingly high mountain, and showed him all the kingdoms of the world and their glory. He said to him, “I will give you all of these things, if you will fall down and worship me.” Then Jesus said to him, “Get behind me, Satan! For it is written, ‘You shall worship the Lord your God, and serve him only.’” Then the devil left him, and behold, angels came and ministered to him.
Mark 1:12-13
Immediately the Spirit drove him out into the wilderness. He was there in the wilderness forty days tempted by Satan. He was with the wild animals, and the angels ministered to him.
Luke 4:1-13
Jesus, full of the Holy Spirit, returned from the Jordan, and was led by the Spirit in the wilderness for forty days, being tempted by the devil. He ate nothing in those days. Afterward, when they were completed, he was hungry. The devil said to him, “If you are the Son of God, command this stone to become bread.” Jesus answered him, “It is written, ‘Man shall not live by bread alone, but by every word of God.’” The devil led him up on a high mountain, and showed him all the kingdoms of the world in a moment of time. The devil said to him, “I will give you all this authority and their glory, for it has been delivered to me; and I give it to whomever I want. If you therefore will worship before me, it will all be yours.” Jesus answered him, “Get behind me, Satan! For it is written, ‘You shall worship the Lord your God, and you shall serve him only.’” He led him to Jerusalem, and set him on the pinnacle of the temple, and said to him, “If you are the Son of God, throw yourself down from here, for it is written, ‘He will give his angels charge concerning you, to mighty guard you;’ and, ‘On their hands they will bear you up, Lest perhaps you dash your foot against a stone.’” Jesus answering, said to him, “It has been said, ‘You shall not tempt the Lord your God.’” When the devil had completed every temptation, he departed from him until another time.

HISTORICAL CONTEXT
The 40-day period in the wilderness for Jesus occurred in the early 1st century AD within the Roman province of Judea. The 'Wilderness of Judea' (ἔρημος Ἰουδαίας) is a desolate, arid region stretching eastward from the Judean mountains towards the Jordan Valley and the Dead Sea. This landscape, characterized by rugged wadis, caves, and sparse vegetation, was historically a place of refuge, solitude, and testing. It was where John the Baptist ministered and where various ascetic groups, such as the Essenes, sought spiritual purity away from the perceived corruption of society. The cultural context of '40 days' held profound significance in Jewish tradition, often denoting a period of divine judgment, purification, or preparation. Examples include the 40 days of rain in Noah's flood (Genesis 7:4), Moses' 40 days on Mount Sinai receiving the Law (Exodus 24:18), the 40 years Israel wandered in the wilderness (Numbers 14:33), and Elijah's 40-day journey to Horeb (1 Kings 19:8). For Jesus, entering such a period after his baptism and before his ministry would have resonated deeply with the Jewish audience, signaling a pivotal, divinely ordained epoch of testing and formation akin to the foundational experiences of their people.
THEOLOGICAL INSIGHT
The theological insight derived from Jesus' 40 days in the wilderness is profound, emphasizing his perfect humanity and divine identity. His fasting and successful resistance to temptation underscore his role as the 'Second Adam,' succeeding where the first Adam failed in the Garden of Eden by choosing obedience over self-will. This demonstrates that human beings, empowered by the Spirit and armed with God's Word, can overcome sin and temptation. It also solidifies Jesus' Messianic identity, revealing that his kingdom would not be established through worldly power or self-serving miracles, but through humble obedience, suffering, and spiritual authority. The forty days following his resurrection, where he taught his disciples about the Kingdom of God before his ascension, further highlight his divine authority and the continuity of his salvific work. These post-resurrection appearances prepared his followers for the outpouring of the Holy Spirit and the establishment of the Church, ensuring that his teachings and mission would continue.
COMMENTARY SYNTHESIS
Rashi (Jewish)
In Jewish tradition, the period of forty days is often associated with significant periods of preparation, cleansing, or divine encounter. For instance, Moses spent forty days on Mount Sinai to receive the Torah (Exodus 24:18), and the generation of the wilderness wandered for forty years (Numbers 14:33). These periods signify an epoch of testing and formation, often leading to a new covenant or a deeper revelation.
Augustine of Hippo (Christian)
Augustine viewed the forty days of Jesus' fasting and temptation as a battle on behalf of humanity. He saw Jesus, as the head of the Church, undergoing this trial to teach his body (the believers) how to fight and conquer temptation. He connected the forty days to the Law (Ten Commandments spread over the four corners of the world, 10x4=40), signifying Christ's fulfillment and victory over what the Law alone could not achieve.
John Calvin (Christian)
Calvin emphasized that Christ's fasting was not merely an act of self-mortification but an example of perfect obedience and a demonstration of his power to overcome Satan through reliance on God's Word. He argued that Jesus, being fully God and fully man, experienced genuine temptation to prove his victory over sin and to teach his followers how to wield the spiritual sword of Scripture.
Didache (The Teaching of the Twelve Apostles) (Early Church)
While not directly commenting on the 40 days of Jesus, the Didache (an early Church document from the late 1st/early 2nd century AD) encourages fasting, specifically 'on the fourth day and on the preparation day' (Wednesday and Friday). This practice reflects an early Christian commitment to asceticism and spiritual discipline, mirroring the example of prolonged fasting set by Christ.
