When the faith of Christ in us is not yet established in its full measure. . . in its maturity of 'our walk of faith'. . . or of our learning the 'faith of Christ' in a certain thing, we usually know the agony of that faith until that faith is established in us by the Spirit Himself. . . (in us, as us).
When it comes to the 'faith of Christ in us' the faith IS the thing itself . . . the very substance. . . the EVIDENCE OF THE THING. Thus when we have "the faith" it IS the evidence of the thing, and it IS a done deal for us.
Others may not see "the substance" as we do, or "know the evidence" because it remains invisible to them. The manifestation in the physical is still to take place for all to see. Nevertheless we KNOW we have The Thing Spoken of for the Spirit himself IS our witness.
