‘A Christianity in which there is only God the Father, but not Christ as a living Son actually cancels discipleship. In that case there will be trust in God, but not discipleship … Discipleship is a commitment to following Christ. Because Christ exists, he must be followed. An idea about Christ, a doctrinal system, a general religious recognition of grace or forgiveness of sins does not require discipleship. In truth, it even excludes discipleship; it is inimical to it. One enters into a relationship with an idea by way of knowledge, enthusiasm, perhaps even by carrying it out, but it is by personal obedient discipleship [that we enter into a relationship with the living Jesus].'
