".....To use an old and hackneyed illustration: suppose a fire in the upper room of a house, and the people gathered in the street. A child is in the upper story: how is he to escape? He cannot leap down - that were to be dashed to pieces. A strong man comes beneath, and cries, "Drop into my arms."
It is a part of faith to know that the man is there; it is another part of faith to believe that the man is strong; but the essence of faith lies in the dropping down into the man's arms.
That is the proof of faith, and the real pith and essence of it. So, sinner, thou art to know that Christ died for sin; thou art also to understand that Christ is able to save, and thou art to believe that; but thou art not saved, unless in addition to that, thou puttest thy trust in him to be thy Saviour, and to be thine for ever."
