Isaiah 40:28-31
Do you not know? To be absolutely certain about something
Have you not heard? To listen or pay attention to
The everlasting God, the Lord, Never ending, infinite, boundless, limitless
the Creator of the ends of the earth One who brought something into existence
Does not become weary or tired. in need of rest as a result of excessive exertion or lack of sleep
His understanding is inscrutable. Perception/impossible to understand or interpret
He gives strength to the weary, the capacity to withstand great force or pressure
And to him who lacks might He increases power. The state of being without or not having enough of something/to make greater in amount, intensity or degree
Though youths grow weary and tired, The early stage in the development of something
And vigorous young men stumble badly, Strong, healthy and full of energy/to lose ones' balance or trip repeatedly, make a mistake or repeated mistakes
Yet those who wait for the Lord Remain in readiness for some purpose
Will gain new strength; Obtain or secure, reach or arrive at, increase the amount or rate of, increase in value
They will mount up with wings like eagles, To become stronger or more intense
They will run and not get tired, Aggressively move in a direction with speed
They will walk and not become weary. Move at a regular and fairly slow pace
So let's put it in the vernacular:
Are you not certain?
Have you not been paying attention?
The limitless God, the Lord,
The One who brought the world into existence,
Does not need rest because He's over-exerted Himself or didn't get a good night's sleep.
His perception is impossible for us to figure out.
He gives the ability to withstand temptation and life to those of us who are over-exerted and tired,
And when we don't have enough strength, He increases the intensity of our power.
Though young believers exhaust themselves,
And even those who are strong and have more energy than the rest of us continue to repeat the same mistakes,
If we remain ready for the Lord to act
We will secure new strength.
We will become more intense and strong like the might seen in the flight of an eagle,
We will move with swift aggression and not tire out,
We will move at a normal pace and not even feel weary.
