In regards to the concept of Trinity in Christianity. I think those who do believe this even though it really does not make sense, therefore should question it, such as three in one and one in three. You see what I am trying to say politely is this (with utmost sincerity) God is very powerful and therefore Jesus (peace be upon him) cannot be part of God although Jesus (peace be upon him) did perform miracles but it was God who was behind the miracles. Another point is that jesus was inside the cosmos. God is separate from his creations. God is outside the cosmos.
