Diligently wait and when you see the prophetic fulfillment, celebrate!
One common pitfall for prophetic ministers is the how long it takes for a prophetic word to come into fulfillment and how prophetic words they have released are fulfilled. John the Baptist is a classic example of a prophet who doubted after seeing Jesus become the fulfillment of the prophetic promises he proclaimed.
Jesus response was, look at my works and blessed is he who is not offended.
The remedy is to accept the prophetic fulfillment by celebrating. We are simply messengers, entrusted with a promise, diligently proclaiming until we can celebrate.
