When Jesus walked the earth he says to repent (Luke 13:5); Jesus says if you obey my teachings you will be saved (Matthew 6:14, Matthew 6:15, John 8:31, John 13:17, John 15:10, John 15:14).
In addition, the disciples after having received the Holy Spirit, they CONTINUED to preach that the people should believe AND REPENT of their sins and call on Jesus' name (Acts 2:38, Acts 5:31, Luke 24:47, Acts 3:19,) and, even PAUL HIMSELF PREACHED REPENT AND BELIEVE TO BE SAVED (Acts 17:30; Acts 20:21, Acts 26:20, 2 Corinthians 12:21 ).
When Jesus died, rose again, and ascended to heaven, he taught to obey and repent, Revelation 3:3, Revelation 14:12, Revelation 2:5, Revelation 3:19, Revelation 9:20,21, Revelation 16:10, 11.
