Around age thirty, Yeshua had specifically sought out John to be baptized. "Baptize" is a transliteration of the Greek word meaning to submerge. The baptism is generally considered to be the start of his ministry. Submerging and ritual bathing had always been a part of Jewish tradition since the days of Moses; especially for ritual cleanness. That’s generally thought to be because of the poor sanitary condition thousands of years ago.
But John had preached a new kind of baptism: to clean the soul. According to Christian philosophy this kind of baptism also was prophetic. It represented the later death burial and resurrection that Yeshua was to go through.
When he found John, he was at first reluctant to do the deed. “I would need to be baptized by you, and yet you come to me?”
But Yeshua replied, "It should be done, for we must carry out all that God requires." So John agreed to baptize him.
All three of the synoptic gospels say that it was a spiritually significant moment for Yeshua and it was remembered as a turning point in his life.
Following the baptism Yeshua was driven into the wilderness for Satan to test him. Specifically Satan tested Yeshua with tuning rocks into bread during his fasting, to jump from a high point in the temple for all to see God rescuing him, and to sell his soul for physical power. This event has been the source of much debate, and speculation over the centuries.
Most American Christians look for a secular meaning to what the particular sin Satan was trying to get Yeshua to commit. The most typical answers seem to be that in the first, Satan wanted him to use his powers for selfish purpose, the second was suicide, and the third was to worship Satan. Reading the passage in Greek offers very few extra insights.
One common interpretation that I like is that Satan was tempting Yeshua with three inferior paths for becoming the messiah. The first was in being a humanitarian, something he did do to an extent anyway -- to which Yeshua responded: Man does not live on bread alone, but on every word that comes from the mouth of God. The second was in becoming a conservative preacher showing off great feats of God -- to which Yeshua responded: Scripture says, Do not put God to the test. The third and most obvious was as a secular king, and something the Jews were expecting from him anyway -- to which Yeshua responded: We are to worship and serve only
God.What do you think what the purpose of Jesus' baptism? Why do you think Satan tempted Jesus in the desert?
