But those who trust in the Lord will find new strength. They will soar high on wings like eagles. They will run and not grow weary. They will walk and not faint. (Isaiah 40:31, NLT) emphasis added
Kings will be your attendants, And their princesses your nurses. They will bow down to you with their faces to the earth. And lick the dust of your feet; And you shall know [with an understanding based on personal experience] that I am the Lord; For they shall not be put to shame who wait and hope expectantly for Me. (Isaiah 49:23, AMP) emphasis added
For the Scripture says, “Whoever believes in Him [whoever adheres to, trusts in, and relies on Him] will not be disappointed [in his expectations].” (Romans 10:11, AMP) emphasis added
Then the Lord said to me, “You have seen well, for I am [actively] watching over My word to fulfill it.” (Jeremiah 1:12, AMP) emphasis added
