The only certainty in my life was these five kids around me.

Probably, but the only certainty would come when people tried it.

Perhaps the only certainty about Sunday's game is that it will be a war.

The only certainty is that she herself was not the child's mother.

The only certainty is that almost nothing will be as it was last year.

The only certainty was that they would not remain still.

The only certainty was that time for them would go on.

For the moment, though, the only certainty seems to be uncertainty.

The only certainty was that there would have been no marriage.

His only certainty was that he'd know exactly what to do when the time came.
