The trouble is that the whole 'accept Christ' attitude is likely to be wrong. It shows Christ applying to us rather than us to him. It makes him stand hat-in-hand awaiting our verdict on him, instead of our kneeling with troubled hearts awaiting his verdict on us. It may even permit us to accept Christ by an impulse of mind or emotions, painlessly, at no loss to our ego and no inconvenience to our usual way of life.
The cross where Jesus died became also the cross where His apostle died. The loss, the rejection, the shame, belong both to Christ and to all who in very truth are His. the cross that saves them also slays them, and anything short of this is a pseudo-faith and not true faith at all.
Churches are more prosperous than at any time within the past several hundred years. But the alarming thing is that our gains are mostly external and our losses wholly internal; and since it is the quality of our religion that is affected by internal conditions, it may be that our supposed gains are but losses spread over a wider field.
