To accept Yeshua as your Lord and Savior is only the beginning. Yeshua says that He is the Alpha and the Omega, the beginning and the end. (Rev. 1:8) When we accept Him into our hearts that is the Alpha, the beginning. We must continue forward and "go" in our learning as talmidim.
A disciple during the time of Messiah Yeshua on earth, would learn from his Rabbi/teacher and emulate his every move. He would learn his way of teaching, his way of living. He would strive to be like his teacher memorizing his every word.
Like the disciples of old, we must be disciples of Messiah Yeshua, emulating His life. To know the answer "What Would Jesus Do". A disciple is a student, and we are students of His Word.
