Jesus started his evangelistic campaign with words to the effect that it was God's timing for good news to be proclaimed. The obligation on his hearers was to change their minds about how they related to their culture, and generally, how they viewed the world. He commanded them to believe that God was in the process of inaugurating his kingdom on earth (Mark 1:14-15). He had sent Jesus to spread the content of this proclamation, starting in Israel. The essence of it was that God loves his creation and wants to save us from our sins (Matthew 1:21; John 3:16-17).
Jesus first gathered a team of 12 and later 72 to preach. The Greek word for preacher means herald, public messenger or publisher. Signs and wonders were an integral part of evangelism (Luke 10:17). The "full gospel" includes healing as well as the forgiveness of sins. The teachers of Judaism were scandalised by Jesus' claim that he had authority to forgive sins but they were silenced when he healed the paralised man (Mark 2:5-12). Evangelists in the 21st century still preach forgiveness of sins in Jesus' name. In many evangelistic campaigns signs and healings are still witnessed (Mark 16:15-18).
In the beginning of his ministry Jesus did not want much publicity. Several times he got into a boat and went to the other side of the lake to escape the crowds. On one occasion he was so tired that he took the opportunity to have a nap while a storm was raging (Matthew 8:18, 24). Nevertheless many who were healed did not obey his instruction to keep it to themselves and the priests (Mark 1:43-45). After their first round of evangelism, even the apostles were swamped with people wanting their attention (Mark 6:30-31).
But about six months before his last Passover Jesus started to draw attention to himself by publicly, in the temple, making statements which were regarded as outrageous. "He proclaimed that he could provide "wells of salvation" (Isaiah 12:2-4; John 7:37-38). He also claimed to be "the light of the world", that God had sent him, that he could grant eternal life, that he was God's son, that he had existed before Abraham was born and that he was the Good Shepherd (John 8:12, 42, 51, 54, 58; 10:7, 11). The Good Shepherd was a title describing attributes of JHWH in Psalm 23. After this he left Jerusalem for a time because there had been several attempts to stone or arrest him (John 10:31; 10:39-40).
When Jesus entered Jerusalem on a donkey in the week preceding the Passover feast, a great crowd accompanied him. They treated him like a king and quoted phrases from the Hallel (Psalms 113-118). The Jews used to sing the Hallel when they made their pilgrimage to Jerusalem for the feasts. The phrases "save LORD" (Hosanna JHWH in Hebrew) and "blessed is he who comes in the name of the LORD" occur in Psalm 118:25-26. These were shouted by the crowd who also replaced "LORD" with "son of David" (Mark 11:9).
There were Pharisees in the crowd who wanted Jesus to stop the jubilation because they thought it was blasphemous. But it was an occasion in which the rightful King was acknowledged and the stones would have praised him if the people had refused. Jesus was overcome with grief that the leaders of Jerusalem did not recognise him, the Prince of Peace (Luke 19:39-42).
During this week Jesus did his utmost to publicise his presence. He was successful. On the road to Emmaus, Cleopas was surprised that anyone in Jerusalem might not have heard about the happenings over Passover (Luke 24:18). About 30 years later Paul was convinced that king Agrippa must have known about Jesus because "these things didn’t happen secretly in some out-of-the-way place" (Acts 26:26). Even pagan historians knew about Jesus (https://reasonsforjesus.com/a-list-of-extra-biblical-sources-for-the-historical-jesus).
Jesus' last words to the Pharisees were that Jerusalem would not see him again until the day they say "Blessed is he who comes in the name of the Lord" (Matthew 23:39). Some Bible scholars are of the opinion that the leaders of Jerusalem will come to the realisation that Jesus is their Messiah. Then they will exclaim that phrase in Hebrew: Baruch Haba B'Shem Adonai. But before that would happen, Jesus' followers were to continue preaching the good news of the Kingdom, starting in Jerusalem and including the ends of the earth (Luke 24:47; Acts 1:8).
