Isaiah 40:29

but He said to me, "My spiritual strength is sufficient, for it is only by means of conscious weakness that perfect power is developed."

I can do anything through Him who gives me strength.

then you will be perfectly empowered by His glorious might for every sort of joyous endurance and forbearance,

stopped the force of fire, escaped from dying by the sword, out of weakness found great strength, grew mighty in war, put foreign armies to flight.

He giveth power to the faint; and to them that have no might he increaseth strength.

but He said to me, "My spiritual strength is sufficient, for it is only by means of conscious weakness that perfect power is developed."

I can do anything through Him who gives me strength.

then you will be perfectly empowered by His glorious might for every sort of joyous endurance and forbearance,

stopped the force of fire, escaped from dying by the sword, out of weakness found great strength, grew mighty in war, put foreign armies to flight.
