Writers, can we agree that every religion seeks God?

I am on a new journey to learn more about religions otherwise foreign to me. Recognizing my limitations, I humbly make this attempt to express where I am now and to seek other writers along this pathway. 

Through different ways and histories, cultural and otherwise...religions claim to 'seek God.' This is something we share. "Seek My face," God has said in Hebrew scriptures (for example, Psalm 27:8).  

Literature is full of cultural and religious beliefs colliding due to blindness about  key  similarities. For example, in The Last Mughal (I am half-way at over 400 pages), the destruction of the Mughal dynasty in Delhi, India, 1857, is connected to belief as much as to political and power conflicts. They are inherently interwoven, and the emperor's court aimed to be tolerant of Christian presence. At least at the beginning and compelled to allow their presence.     

Followers saw their Delhi Mughal as being close to or second to 'God, the Almighty.' Yet, did this mean that the Mughal would have closed his mind against conversation about 'the Son of God'? I cannot help wondering about his reaction, if he had heard of Jesus as the Lord via a friend's discourse rather than a foreigner's conquering presence.

John 3:16* is truth without labels. It must have been familiar to British Christians occupying India in the 19th century. In that scripture, God shows that He is reaching out to everyone, regardless; and cultural and religious identities are not mentioned.  

Jesus said (John 3:16), "God so loved the world that He gave His only begotten Son that whosoever believes on Him shall be saved" (italics added). God speaks in love to 'the world,' of His 'only begotten Son.' The receiving audience is the world; the subject and gift is the Son. The Son is not mentioned with cultural, traditional, religious, or national connections. The Son is 'culture-free' in God's broad scope for the world. Jesus speaks for God without judging other "belief systems," as they are called today. See John 3:17.      

India, 19th century, included intellectual, literate, productive, artful, and wealthy persons and groups that, at first, accepted or allowed the presence of British military and East India Company ('the Company') workers. These were prominently allied with Christian faith. British families lived in homes designed to please them; they worshiped at churches built according to Indian or British design. Yet, British military leaders that harshly disrespected their hosts' beliefs and culture/way of life refused to consider them even as 'hosts.' An important few preferred to see them as 'the occupied,' or even 'the conquered.' Inevitably, the term 'Christian' and 'cruel conqueror' became synonymous. No wonder. The Mughal Dynasty of Delhi would be killed off cruelly by those identified with 'Christianity.'     

A Muslim friend from India gave my husband and me a copy of The Last Mughal. As Christian and American, I find the story helps to strengthen my desire to know better the beliefs of other religions. I maintain the whole and basics of Christian faith while wanting to know more about those who are neighbors or members of the wider community, in positive ways.  I will know them, I believe, as friends, at least a few. Not knowing any atheists free of argument or anger, I likely will not have dialogue there. Otherwise, the love of Christ compels this desire' to learn about how 'seeking God' has shaped others' beliefs. Seeking those loved of God strengthens my desire to seek Him continually through Christ and His ways. "God so loved the world.... I did not come to judge the world...." 

If you are writing about these themes, I would like to know about your work.

*If the Bible is new to you, there is Old Testament (Hebrew and Aramaic, originally) and New Testament (original in Greek). The books have names, e.g. 'Genesis' or 'John' and chapter and verse numbers (e.g., John 3:16; or 3.16).
