What is reality? Whatever you have ever known of it is merely your knowledge. Whatever you have ever understood about it is merely your understanding. Whatever you have ever perceived about is is merely your perception.
Your knowledge, understanding and perception are merely processes of your own consciousness. Therefore the sum total of your reality is merely a process of your consciousness.
If you perceived reality differently, then your reality would be different. If you understood reality differently, then your reality would be different. If you knew reality in a differently, then your reality would be different.
Whatever your reality appears to you to be right now, it is that way, because you understand, know, perceive, believe, sense, reason, interpret, deduce or feel it to be that way.
And all those processes - understanding, knowledge, perception, believing, sensing, reasoning, interpretation, deduction, feeling etc etc - are processes of your own consciousness.
And if you change your thoughts, your reality changes.
The only questions are the nature, extent and directions in which you are actually able to change your thoughts. For example, you might believe in God, but your belief might not be that strong or deep.
Thus it would probably be very difficult, for example, for you to believe that God will empower you in this very instant and you would be able to perform miracles such as healing the sick. But evidently the apostles were at that level, they had that kind of faith (faith being a mental attitude, and attitude basically being thoughts) and therefore they did perform such miracles.
