“Christian”
Jesus never used the word “Christian”. The word he used to describe those who belong to Him was the word “disciple”. In Luke 14:27 He said, “And whoever does not carry their cross and follow me cannot be my disciple.” You can’t be a disciple unless you follow Jesus. And it’s impossible to follow Jesus without doing what he says. Jesus said “Why do you call me, ‘Lord, Lord,’ but do not do what I say?” (Luke 6:46).
