For me, the most simplest definition, I think the one that gets to the core of what discipleship is about, is becoming more and more like Jesus, like the one I love. The way we worship Jesus is by obeying Him. He calls us to utter obedience, because in the Hebrew mind, the way you worship is to obey. It’s not simply giving words. It’s actually becoming like. In a sense, my becoming like Jesus is what I’m designed eternally to be like. When we shall see Him, we shall be like Him.
