Jezus must tell the people about the gospel and that they live in sins..

Jezus said to His disciples go out and preach the people the the gospel...

Many many people listen to the Man of Son Jezus and do believe that they were a sinner in their life..

Jezus tell the people about their sins and preach the gospel.. and a lot of them came to a believer in Jezus (Yesua)

Jezus let baptist Himself as the first but without sins , so the baptising was and is for every human on earth who lives in sins and make a new start in his or her life and ask the Farther in Heaven, Lord will you vergive and pray with me.... Jezus is the "only" Way...
