What does Isaiah 40:23 Mean?

Context Summary

Day changes to night, and as the twilight deepens, the stars come out in their myriads, Isaiah 40:26. To the poetic eye of the watcher, they appear as a vast flock following the shepherd, who calls each by its name. Not one falls out of its place, or is lacking. Will Jehovah do so much for stars and nought for men? Will He not have a name for each? Will He not guard and guide each? If He has sustained the orbs of light in their mighty rounds, will He fail the poor soul that clings to His feet?

They that wait on God change their strength. In their earliest days they rely on the energy and vigor of youth, on their blameless, unstained character, in the consciousness of their glorious manhood; but as years pass, they come to count all these as refuse in comparison with Jesus Christ the Lord, Philippians 3:8. Notice the order in Isaiah 40:31! At first sight we should have expected that it would advance from walking to running, and so to flying. But that order is reversed. It is more difficult to walk than to mount! Every cyclist will tell you that the hardest task is to keep your cycle at walking pace. [source]
