I was agnostic growing up until I started looking at how orderly the universe is. I started talking to a Christian friend and they invited me to their church. When I surrendered that I didn't know as much as I thought I opened my heart and that's when I found Jesus and gave my life to the Lord. Atheists operate with their heads and a blind heart. It's sad.

Beginning must have a cause

BE (being aka effect) GIN/GEN (generation aka cause)

even if our universe turns out to be one part of a multiverse

Verse/verto - "to turn"...it's ignoring the delineation of cause to effect which turns uni into multi aka together.
