Why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen Him go into heaven. – Acts 1:11

“This same Jesus.” Why, that must have meant that He who is in heaven is the same Christ who was on earth, but it must also mean that He who is to come will be the same Jesus that went up into heaven... He will possess the same tenderness when He comes to judge, the same gentleness of heart when all the glories of heaven and earth shall gird His brow. Our eye shall see Him in that day, and we shall recognize Him not only by the nail-prints, but by the very look of His countenance, by the character that gleams from that marvellous face; and we shall say, “‘Tis He! ’tis He! the self-same Christ that went up from the top of Olivet from the midst of His disciples.”

Despisers tell us nowadays, “Your cause is done for! Christianity is spun out! Your divine Christ is gone; we have not seen a trace of His miracle-working hand, nor of that voice which no man could rival.” Here is our answer: We are not standing gazing up into heaven, we are not paralyzed because Jesus is away. He lives, the great Redeemer lives; and though it is our delight to lift up our eyes because we expect His coming, it is equally our delight to turn our heavenly gazing into an earthward watching, and to go down into the city, and there to tell that Jesus is risen, that men are to be saved by faith in Him, and that whosoever believeth in Him shall have everlasting life. We are not defeated; far from it: His ascension is not a retreat, but an advance. His tarrying is not for want of power, but because of the abundance of His long-suffering. The victory is not questionable. All things work for it; all the hosts of God are mustering for the final charge. This same Jesus is mounting His white horse to lead forth the armies of heaven, conquering and to conquer. ~ C.H. Spurgeon
