The simplest definition of a Christian is one who follows Christ. This was his own definition: "My sheep hear my voice, and follow me." "I am the way and the truth and the life." "Come to me, all ye who labor and are heavy laden." When Mary sat at the feet of Jesus, and heard his words, he said that she had chosen the good part, and had done the one thing needful.
