I do not mean, as is sometimes meant, by that statement that a man has to try to force his understanding into the attitude of accepting religious truth, in order that he may have an experience which will convince him that it is true. I mean a very much simpler thing than that, and a very much truer one, viz. this, that unless we trust to Christ and take our illumination from Him, we shall never behold a whole set of truths which, when once we trust Him, are all plain and clear to us. It is no mysticism to say that. What do you _know_ about God?—I put emphasis upon the word 'know'—What do you know about Him, however much you may argue and speculate and think probable, and fear, and hope, and question, about Him? What do you know about Him apart from Jesus Christ? What do you know about human duty, apart from Him? What do you know of all that dim region that lies beyond the grave, apart from Him? If you trust Him, if you fall at His feet and say 'Rabbi! Thou art my Teacher and mine illumination,' then you will see. You will see God, man, yourselves, duty; you will see light upon a thousand complications and perplexities; and you will have a brightness above that of the noonday sun, streaming into the thickest darkness of death and the grave and the awful hereafter. Christ is the Light. In that 'Light shall we see light.' And just as it needs the sun to rise in order that my eye may behold the outer world, so it needs that I shall have Christ shining in my heaven to illuminate the whole universe, in order that I may see clearly. 'Believe and thou shalt see.' For only when we trust Him do the mightiest truths that affect humanity stand plain and clear before us.
And besides that, if we trust Christ, we get a living experience of a multitude of facts and principles which are all mist and darkness to men except through their faith; an experience which is so vivid and brings such certitude as that it may well be called vision. The world says, 'Seeing is believing.' So it is about the coarse things that you can handle, but about everything that is higher than these invert the proverb, and you get the truth. 'Seeing is believing.' Yes, in regard to outward things. Believing is seeing in regard to God and spiritual truth. 'Believest thou? thou shalt see.'
Then, thirdly, there is light here about another matter, the connection between faith and progress. 'Thou shalt see greater things than these.' A wise teacher stimulates his scholars from the beginning, by giving them glimpses of how much there is ahead to be learnt. That does not drive them to despair; it braces all their powers. And so Christ, as His first lesson to these men, substantially says, 'You have learnt nothing yet, you are only beginning.' That is true about us all. Faith at first, both in regard to its contents and its quality, is very rudimentary and infantile. A man when he is first converted—perhaps suddenly—knows after a fashion that he himself is a very sinful, wretched, poor creature, and he knows that Jesus Christ has died for him, and is his Saviour, and his heart goes out to Him, in confidence and love and obedience. But he is only standing at the door and peeping in as yet. He has only mastered the alphabet. He is but on the frontier of the promised land. His faith has brought him into contact with infinite power, and what will be the end of that? He will indefinitely grow. His faith has started him on a course to which there is no natural end. As long as it keeps alive he will be growing and growing, and getting nearer and nearer to the great centre of all.
