I feel this is how God watches over His word, faithfully and meticulously bringing it to pass; ensuring the word is fulfilled in the perfection of His will. Although from our point of view, we might feel the fulfillment is being delayed, or disrupted. We may feel we have lost time or the opportunity we saw had disappeared. But God, who sees everything beyond what we can see or imagine, He remains in charge and ensures that at the appointed time, His word is fulfilled. His timing is never late or early. He is always right on time. And nothing can change His plans.
