Heres Dietrich Bonhoeffer, writing in 1937- The Cost of Discipleship, but it could be Dallas Willard -
'Discipleship means adherence to Christ, and, because Christ is the object of that adherence, it must take the form of discipleship. An abstract Christology, a doctrinal system, a general religious knowledge on the subject of grace or on the forgiveness of sins, render discipleship superfluous, and in fact they positively exclude any idea of discipleship whatever, and are essentially inimical to the whole conception of following Christ. With an abstract idea it is possible to enter into a relation of formal knowledge, to become enthusiastic about it, and perhaps even put it into practice; but it can never be followed in personal obedience. Christianity without the living Christ is inevitably Christianity without discipleship, and Christianity without discipleship is always Christianity without Christ.'
Duncan Campbell -1956 'I want to say reverently and humbly that for me the greatest reality, the greatest fact in life is just the presence of the Lord Jesus.And I love Him; that to me is greater than preaching, it is greater than seeing revival...the greatest thing of all is just to have fellowship with Jesus'
Lord Jesus, I want to be able to say that too, and mean it. Amen
