Jesus said unto her, Said I not unto you, that, if you would believe, you should see the glory of God?  -John 11:40

The young Christian, at first, is not constant in his faith- a little wind comes, and he shakes, when he gets to be an old Christian it will take old Boreas, with fifty of his winds, to move him. Do you not feel, my dear friends, that you want faith to be increased in its intensity? Would you not sing with Watts:

“Oh! that I had a stronger faith,
To look within the veil;
To credit what my Saviour saith,
Whose word can never fail?”

Your poor little faith cannot see many yards before it, for there are clouds of darkness all around; but strong faith can climb the hill that is called “Clear,” and from the top thereof can see the celestial city, and the land that is very far off. Oh! may God increase your faith to such a degree, that you may often have visions of heaven”-that you may sweetly sing, as Moses might have done at the top of Pisgah,-

“Oh! the transporting rapturous scene
That rises to my sight.
Sweet fields arrayed in living green,
And rivers of delight.”

That you may climb up there, bathe your eyes in splendor, plunge your soul in rivers of bliss, and be thoroughly transported and carried away by visions of that state of beatitude which shortly shall be yours, let me exhort you to cry to the Lord, “Increase my faith” in its power of realizing heaven and in every other way. ~ C.H. Spurgeon
