Is there a god and can he help me?

God is a myth created by educated men to keep the uneducated in order. 

Yes there is, and have you asked Him to help you?

No He cannot help you because He cannot join Himself to sin.

You must first have your sin problem dealt with.

Yes and yes...............

No, and hence no

No, and by way of consequence, no.

Yes, Allah Ar-Rahman, Ar-Rahim, The Most Compassionate, The Most Merciful can help you and if you invoke Him without associating any false partners with Him. See an interesting short link in the comments. I will add another one you should see and I may add other links later too.

There is a God of heaven, he wrote us a book so we can have all the answers. Christ answered all of life, for sinners and holy angels.
