In Christianity, as in Judaism and Islam, God is the one Creator of the Universe. This one God is recognized by some Hindus and Brahma.
I had a deep theological conversation with my father-in-law, who is a Christian theologian. He said that if we study the Bible and the early Christian church closely, we will see that anyone who believes that people and the world can be redeemed (made healthy and whole) can be saved.
Jesus said, "I am the Way, the Truth, and the Life, and none shall reach the Father but by me." Many people take this to mean that one has to believe in Jesus. But he never said that. He taught us to pray "Our Father." So God the Creator is the Father of all, Jew, Christian, Muslim, Hindu, Buddhist, believer in any faith and non-believer alike.
One Christian view is that anyone who shares love in this world becomes loving as Jesus was loving. We meet him on the Way to God.
Love you now, and see you there!
