Why should I pick Christianity?

So he came home with some brochures to promote Christianity. He may have guessed we are muslims. I wanted to ask and tell him many things....

1. Do you believe in the bible?
2. Where in the bible has Jesus himself claimed divivinity?
3. Where is the word "trinity" mentioned in the bible?
4. How can God have a son and then not be able to save him?

We are muslims and to those of us who understand what we believe our faith is unshakeable.
Jesus did not die on the cross - Allah never let that happen to him. He is one of our beloved prophets.

Say: He is Allah, the One and Only!
Allah, the Eternal, Absolute;
He begetteth not nor is He begotten.
And there is none like unto Him.

Bring your description of God, that matches the above criteria and we will accept him!
