If someone asked you to give them another word for 'God', you could use the word 'Presence', for that is what God is. When Moses asked Yahweh his name, Yahweh replied, "I am who am" and this means 'I am present'. God is really saying,
'I shall be there for you.' God is intimately present to everything, and especially to us.
Jesus's name is Emmanuel, which means 'God is with us'. Matthew's Gospel ends with the marvellous statement:
“Know that I am with you always; yes, to the end of time.”
