Genesis 21:2
“For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.”
KJV
Read in Genesis 21Meaning
The emphasis falls on the promised son arriving at the appointed time despite the couple's advanced age.
Read carefully
The exceptional conception belongs to this particular biblical narrative and is not a medical forecast or general rule for fertility.
Reflection
The verse portrays delayed promise fulfilled, while readers should resist using it to judge those whose hopes remain unanswered.
