But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
Isaiah 40:31 KJV
“They that wait” are not passively waiting in hopes that God will do something. Believers wait with the expectation of biblical hope. This is hope that has the substance of faith’s claim on biblical promise.
Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1 KJV
The overcoming victory pictured in Isaiah 40:31 is only found in this kind of waiting.
Wait upon the Lord with great expectation the His Word is true and will come to pass.
So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. Isaiah 55:11 KJV
