Let’s look at that term wait. It is from the Hebrew verb kah-wah meaning “to twist, stretch.” The noun form means “line, cord, thread.”
A vivid picture emerges here.
[Kah-wah] is a verb describing the making of a strong, powerful rope or cord by twisting and weaving ourselves so tightly around the Lord that our weaknesses and frail characteristics are replaced by His power and unparalleled strength. It describes very literally the truth of what has been termed the “exchanged life.”
As we wait on God, our weakness is exchanged for His strength.
Strength and courage are developed during a trial, not after it is over.
