It is understandable to feel frustrated and unsettled when you are denied without an immediate clear explanation, and it is right to bring that desire for clarity before the Lord.
There are times when the official record seems silent at first, and it can be tempting to think there is no reason or no answer. History has shown that what looks like a missing piece at first often becomes clear when more information comes to light. What Scripture records has been shown to be trustworthy, even when outside records seemed at first to be incomplete or to use different terms, and further understanding has brought confirmation. In the same way, a denial that feels abrupt now does not mean a clear reason will not come. You have a right to receive a written explanation, and that documentation usually follows within a short time.
It is also encouraging to remember that God sees and speaks with clarity about things before they happen, while we are still looking at them from our limited present view. You may not see the whole picture yet regarding this account, but He does, and He is faithful to guide you as you wait for answers. Other accounts that seem similar on the surface can actually help confirm what is true when they are compared carefully, and in your case the coming explanation will help you understand what happened and what steps to take next.
I pray that the Lord will provide the clear reasons you are seeking, that any confusion in language or records will be made plain, and that you will have peace while you wait. I pray that He will open the right door for your financial needs, give you wisdom to review any report or letter that comes and to take the next practical steps, and remind you that He cares for every detail of your life and will provide for you. I ask this in the name of Jesus, trusting His truth and His provision.
