fulfil all righteousness
Matthew 3:15
3:15 fulfil all righteousness. Jesus had no need for repentance or forgiveness, but was baptized “to fulfill all righteousness.” That is, it was right for men to be baptized, and Jesus would leave us “an example, that ye should follow His steps” (I Peter 2:21). Furthermore, although He “knew no sin,” He knew He would be made sin for us (II Corinthians 5:21), and thus would have to die, be buried and then rise again; His baptism would testify to this at the very beginning of his ministry.
