If you thread two keys onto a single key ring, is either key more complete after it is joined with the other?
No.
And neither will you be if you’re single and hoping to be married one day.
“Singlehood” is often synonymous with “incomplete.” But Adam and Eve weren’t created as a couple. God created Adam first, as a single, an individual. He was given a purpose in God’s creation prior to Eve becoming his wife.
