Questions for Christians about the trinity?

All your questions are relevant and many others have wondered the same thing. All I can say is God sent Jesus to be born as a baby through the virgin Mary although he was without sin and could perform miracles and he was God in the flesh he also prayed and talked to God which means to me as Jesus was separate but also one with God. Since he was human in the since he was born Jesus could feel pain and needed sleep as humans do. Of course my logic is opinion and can be refuted it is hard to wrap your mind around such things.
