Faith Makes the Real Things to Become Real in my Experience
Watchman Nee If I am blind I cannot distinguish color, or if I lack the faculty of hearing I cannot enjoy music. Yet music and color are in fact real things, and their reality is unaffected by whether or not I am able to appreciate them. Now we are considering here the things which, though they are not seen, are eternal and therefore real. Of course we cannot substantiate Divine things with any of our natural senses; but there is one faculty which can substantiate the "things hoped for", the things of Christ, and that is faith.
Faith makes the real things to become real in my experience. Faith 'substantiates ' to me the things of Christ. Hundreds of thousands of people are reading Romans 6. 6: “Our old man was crucified with him". To faith it is true; to doubt, or to mere mental assent apart from spiritual illumination, it is not true.
Let us remember again that we are dealing here not with promises but with facts. The promises of God are revealed to us by His Spirit that we may lay hold of them; but facts are facts, and they remain facts whether we believe them or not. If we do not believe the facts of the Cross they still remain as real as ever, but they are valueless to us. It does not need faith to make these things real in themselves, but faith can 'substantiate' them and make them real in our experience.
