No, God is not like smoke or a gas and I really cannot explain exactly how He can be everywhere at once. But I do know that somehow a person praying in England at midnight is heard by God, as is a person praying in Argentina at the same time: 7.00 pm. Or someone is Australia when it is 7.00 am in the morning. Somehow, God hears everywhere. I shall find out how He does when I get to heaven. (Sorry, but I can’t write to you from there!!)
There are some things humans cannot, or are not meant to understand.
They can understand jokes. Here is one: “Why do mountain climbers always rope themselves together?” A: “So the sane one cannot turn around and go home.” (I do not climb mountains!)
