According to the Bible, Jesus was baptized by John in order to fulfill all righteousness. This means that Jesus' baptism was an important step in His ministry and obedience to God's will.
Baptism is a symbolic act that represents a person's commitment to God and their identification with the community of believers. In Jesus' case, His baptism by John was a public declaration of His mission to save humanity and to identify with sinners.
Additionally, by submitting to baptism, Jesus was also setting an example for His followers to follow. Jesus' baptism was a way of showing His followers that they too should be baptized and publicly identify with Him.
Therefore, Jesus' baptism was not done to confirm John's power, please the Jews, or identify with the sinners, but rather to fulfill His mission and set an example for His followers.
