He prepared for his life and his ministry by fasting 40 days.
He fought temptations with just words, but they were Gods words.
“4 Then Jesus was led by the Spirit into the wilderness to be tempted[a] by the devil. 2 After fasting forty days and forty nights, he was hungry. 3 The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.”
4 Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’[b]”
5 Then the devil took him to the holy city and had him stand on the highest point of the temple. 6 “If you are the Son of God,” he said, “throw yourself down. For it is written:
“‘He will command his angels concerning you,
and they will lift you up in their hands,
so that you will not strike your foot against a stone.’[c]”
7 Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’[d]”
8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9 “All this I will give you,” he said, “if you will bow down and worship me.”
10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’”
11 Then the devil left him, and angels came and attended him.
When his cousin John was arrested and sent to prison, awaiting the death penalty he took up where John left off.
“Repent, for the Kingdom of heaven is near.”
He began calling disciples. He said to four fishermen, “come follow me, and I will make you fishers of men.” One of those first four would be dead in 4 years.
(For the sake of accuracy James was probably killed in 44 AD. He may have been run through or disemboweled or Beheaded. He was killed for believing that Jesus rose from the dead. Killed for following Jesus.
“2 He had James, the brother of John, put to death with the sword.”)
He started teaching and preaching the “good news”. He then began healing everyone who was sick or lame, demon possessed, or even just hurting.
“Jesus went throughout Galilee, teaching in their synagogues, proclaiming the good news of the kingdom, and healing every disease and sickness among the people. 24 News about him spread all over Syria, and people brought to him all who were ill with various diseases, those suffering severe pain, the demon-possessed, those having seizures, and the paralyzed; and he healed them. 25 Large crowds from Galilee, the Decapolis,[g] Jerusalem, Judea and the region across the Jordan followed him.”
Jesus. Who is he? How did he do this stuff? Why did he do this stuff? What am I supposed to do with him?
Life is the test. The questions are listed above. You have the rest of your life to finish the test. The thing is, no one knows how long that is.
This is how I answered those questions:
“Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst.”
