The long taut string of God's Promises yet to be fulfilled

Today I saw a long taut string with the sense of a weight at the end which I believe represents the promises God has made us but we haven't seen yet. Hebrews 11:1 tells us : "Now faith is the assurance of things hoped for, the conviction of things not seen.". Don't let's lose heart or look at others with envy for what they have but we don't have. Hold on to the figurative string of God's promises. They are going to be fulfilled in due course.
