Everything that is hidden we must believe in it as Allah (swt) tells us about. For example when the Throne, the Balance, Preserved Tablet .. are mentioned, we just know that all of these are in heaven and our proof is the Hearing and receiving from the Trusted and the Honest. Hence, these matters are revealed from Allah (swt) so no need to investigate about their conditions as they are above our perception. However, Allah (swt) inform us about the Throne but we do not know how it looks like.
Not realizing things is not a condition of not being there. The important thing is your confidence in whom he informs you, and the One who told us is Allah (swt) and the Messenger (saws).
As sometimes, in this worldly life, we are unable to describe some of the developed sensible things as the electricity, consequently how do we hope to describe the hidden matters related with Allah (swt).
الْمَجِيدُ (The Most Honorable, The Glorious): It is one of the Attributes and Names of Allah (swt). Meaning whose bounties extend to all the requirements of existence and from this characteristic arises greatness and glorification.
