this is what God has promised us will be fulfilled, for he is a Man to lie, and all the blessings that He has predestined for us will come true.

From somewhere, God is going to bring what is necessary so that you can do what He has said that you are going to do. You have closed doors, but God has a space and people who are looking for you to give you the victory He promised you. Christ in you is the hope of glory.
