I Peter 1:8-9 says if we believe in the Divine we cannot see, we are to rejoice with joy. It is then that we receive the end of our faith. In other words, only when you believe in the inner Presence of the Kingdom of Heaven and your identity as a child of God can you claim the inheritance that is yours.
For example, let's say you get a letter from the lottery commission stating you've hit a secret jackpot. You know the lottery commission exists, and you know the commission awards huge sums of money to the winners. Yet you have no proof other than a written document stating you are about to become wealthy. At that moment you become excited and full of joy, and you begin visualizing all your desires fulfilled. Well, this is the secret to actualize and manifesting. Believe in that which you have not seen, and rejoice knowing it will manifest.
Affirm: "I AM one with the Divine Presence of God within me. I believe in this Presence and rejoice knowing now faith is the substance of things hoped for and the evidence of things not seen."
