What are the Christian and Sikh views on God’s birth and death?
In the Bible we read that Christ was born to Mary. Whether he was conceived through God himself or his agent angel, his birth is accepted by everybody. The agency of an angel simply proves that God as Jesus was dependent on the angel and Mary for His own birth. In other words God was created by an angel through Mary’s help. His death is also recorded in the Bible (John 19.33, matt 12:46.16:27). So he could not be God because the Bible says that God does not die (Ps 90:2 and I Tim 6:16).39
According to Sikhi God is ਅਕਾਲ ਮੂਰਤਿ (timeless-deathless).
ਤੂ ਪਾਰਬ੍ਰਹਮੁ ਪਰਮੇਸਰੁ ਜੋਨਿ ਨ ਆਵਹੀ ॥
ਤੂ ਹੁਕਮੀ ਸਾਜਹਿ ਸ੍ਰਿਸਟਿ ਸਾਜਿ ਸਮਾਵਹੀ ॥
“You are the Lord of all and do not enter the womb. You create the Universe in Your Will and assimilate it within yourself when you wish otherwise”.
