I think it should be obvious you cannot be a disciple unless you have first accepted Jesus as your Lord and Savior. But can you be saved without being a disciple of Jesus? I don’t think that answer is as clear. Earlier in my faith walk, I probably would have said yes. These days, my answer is leaning towards no.
We could probably trade scriptures all day long trying to prove one side or the other, but at the end of the day, I think the bulk of evidence lands on the fact that to be a believer in Jesus is to be His disciple. This has serious ramifications for the way we live our lives.
