How do you defend a belief in something that is unimaginable?

[I can't imagine a lot of things and coincidentally, I don't believe in them. A square circle is unimaginable. Should I believe that it exists?]

First of all, you must notice that all the philosophers are experts in logic in depth. You should not be hasty and fast in drawing conclusions with such high speed, since such conclusions result in three-dimensional clashes. All your arguments contradict each other if I unveil them slowly in a systematic manner. It will become a very long article and finally, the result would be that you would feel hurt when I show you the mutual contradictions through deep analysis. I do not want to do this and make you more aggressive. Instead, I give the following brief account in a straight manner and request you to understand it directly and simply without causing three dimensional twists and spoiling the basic truth.

You must know that miracles are being exhibited in this world, which are clearly different from magic. If all the miracles had been proved to be magic, the concept of God would have been easily buried long time ago. You have neither observed the miracles nor do you believe the experiences of elder and wiser people, who are greater scientists and scholars in logic than you. The miracle exists as an unimaginable event. Logic cannot touch even the surface of a miracle and hence, the miracle stands as a strong practical evidence for the existence of an Unimaginable Entity, which is called as God. The miracles also prove that they are beyond space and time and hence, the Unimaginable Entity is beyond space and time.

God is only a name given to this Unimaginable Entity. Even the boundary of the universe is unimaginable. The unimaginable square-circle is a different case because both the square and circle are imaginable components of the square-circle. God is unimaginable in-toto as per the analysis of the unimaginable miracles. The person, who performs the miracles, thus becomes the authority to speak on the unimaginable God. Such person possesses God (or the Unimaginable Entity) and His word is taken as the scripture. Everybody tries his best to disprove the miracle but a genuine miracle always really stands as an unimaginable event. The concept of God is built up from this very fact.
