Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. 1John 3:2

You look forward to your experience in heaven, you sing—

“Then shall I see, and hear, and know
All I desired or wished below;
And every power find a sweet employ
In that eternal world of joy.”

You are expecting to see His face, and never, never sin. You are longing to know the secrets of His heart. You believe that in that day you shall see Him as He is and shall be like Him in the world of spirits.  Well, beloved, though Christ does not manifest Himself to us as He does to the bright ones there, have not you and I had manifestations even while we have been in this vale of tears? Speak, beloved; let your heart speak; hast thou not had visions of Calvary; has not your Master sometimes touched your eyes with eye-salve, and let you see Him on His cross? Have you not wept for joy and grief when you saw Him bleeding out His life from His heart for you and beheld Him nailed to the tree for your sakes! O yes! I know you have had such manifestations of Him. And have you not seen Him in His risen glories? Have you not beheld Him there exalted on His throne? Have you not by faith beheld Him as the Judge of the quick and the dead, and as the Prince of the kings of the earth? Have you not looked through the dim future, and seen Him with the crown of all the kingdoms on His head, with the diadems of all monarchies beneath His feet, and the scepters of all thrones in His hand? Yes, you have, and therein you have had foretastes of heaven. When Christ has thus revealed Himself to you, you have looked within the vail, and, therefore, you have seen what is there, you have had some glimpses of Jesus while here; those glimpses of Jesus are but the beginning of what shall never end. Those joyous melodies of praise and thanksgiving are but the preludes of the notes of Paradise. ~ C.H. Spurgeon
