From The Glory of Christ:
In this way Roman Catholics are deceived. They delight outwardly in images of Christ depicting his sufferings, resurrection and glory. By these images they think their love for him grows more and more strong. But no man-made image can truly represent the person of Christ and his glory. Only the gospel can do that.
John writes not only of himself but of his fellow apostles also, ‘We beheld his glory, the glory as of the only begotten of the Father, full of grace and truth’ (John 1:14). Now what was his glory of Christ which they saw, and how did they see it?
It was not the glory of Christ’s outward condition for he had no earthly glory or grandeur. He kept no court, nor did he entertain people to parties in a great house. He had nowhere to lay his head, even though he created all things. There was nothing about his outward appearance that would attract the eys of the world (Isa. 53:14; 53:2-3). He appeared to others as a ‘man or sorrows’.
Neither was it the eternal essential glory of his divine nature that is meant, for this no man can see while in this world. What we shall see in heaven we cannot conceive.
What the apostles witnessed was the glory of ‘grace and truth’. They saw the glory of Christ’s person and office in the administration of grace and truth. And how did they see this glory? It was by faith and in no other way, for this privilege was given only to those who ‘received him’ and believe on his name (John 1:12). This was the glory which the Baptist saw when he pointed to Christ and said, ‘Behold! The Lamb of God who takes away the sin of the world!’ (John 1:29).
So, let no one decieve himself. He that has no sight of Christ’s glory here shall never see it hereafter. The beholding of Christ’s glory is too high, glorious and marvellous for us in our present condition. The splendour of Christ’s glory is too much for our physical eyes just as is the sun shining in all its strength. So while we are here on earth we can behold his glory only by faith.
No man ought to look for anything in heaven if he has not by faith first had some experience of it in this life. If men were convinced of this, they would spend more time in the exercise of faith and love about heavenly things than they usually do. At present they do not know what they enjoy, so they do not know what to expect. This is why men who are complete strangers to seeing the person and glory of Christ by faith have turned to images, pictures and music to help them in their worship.
