Our calling is not primarily to be holy men and women, but to be proclaimers of the Gospel of God. The one thing that is all important is that the Gospel of God should be realized as the abiding Reality. Reality is not human goodness, nor holiness, nor heaven, nor hell; but Redemption; and the need to perceive this is the most vital need of the Christian worker to-day. As workers we have to get used to the revelation that Redemption is the only Reality. Personal holiness is an effect, not a cause, and if we place our faith in human goodness, in the effect of Redemption, we shall go under when the test comes.
Paul did not say he separated himself, but – "when it pleased God who separated me. . ." Paul had not a hypersensitive interest in his own character. As long as our eyes are upon our own personal whiteness we shall never get near the reality of Redemption. Workers break down because their desire is for their own whiteness, and not for God. "Don’t ask me to come into contact with the rugged reality of Redemption on behalf of the filth of human life as it is; what I want is anything God can do for me to make me more desirable in my own eyes." To talk in that way is a sign that the reality of the Gospel of God has not begun to touch me; there is no reckless abandon to God. God cannot deliver me while my interest is merely in my own character. Paul is unconscious of himself, he is recklessly abandoned, separated by God for one purpose – to proclaim the Gospel of God (cf. Rom. 9:3.)
