John Gill Commentary Genesis 18:14

"Is anything too hard for Jehovah? At the set time I will return unto thee, when the season cometh round, and Sarah shall have a son." — Genesis 18:14 (ASV)

Is anything too hard for the Lord ?
&c.] Whose power is infinite; or "too wonderful" ^F24 , so wonderful and beyond all belief, that it can never be thought it will be done by him; and why then should it be thought incredible or impossible that Sarah should have a child, though she is old? Or, is "anything hidden from the Lord" ^F25 ? Nothing can be, not Sarah's laughter. At the time appointed will I return to you, according to the time of
life, and Sarah shall have a son ;
which words are repeated not merely for the confirmation of Abraham's faith, which staggered not, but to remove Sarah's unbelief, and to encourage her faith in the divine promise.
