The following quote brings immediately to mind a passage of Scripture from Isaiah 40:31...."but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint". What a wonderful picture!
"Be like the bird that, pausing in her flight awhile on boughs too slight, feels them give way beneath her and yet sings, knowing that she hath wings." ~ Victor Hugo
