So there were a bunch of people that walked around with Jesus and were with him for the entire duration of his ministry. They were more than just the 12, but these people didn't get the recognition that the others did. They didn't get the authority, the close contact with Jesus, or the respect that the disciples did. But that's not why they went with Jesus.
A lot of times we get sidetracked in what we are doing. We start out serving God because we love Him. Sometimes we get sidetracked by beginning to love how we're serving. Sometimes we get sidetracked by the attention we receive. Whatever the distraction, it takes us away from our true purpose, to love Jesus and serve Him. JM
