What does Hebrews 11:12 mean?
The general pattern of biblical faith is to trust our future to God, despite not having perfect knowledge of what will happen next (Hebrews 11:1). This part of the book of Hebrews describes examples from the Old Testament, showing that God rewards those who trust Him, even though they cannot see all of the details in how God plans to make good on His promises (Hebrews 11:2). Among these examples were Abel, Enoch, and Noah, as well as Sarah and Abraham.Here, the reference to Abraham is especially important. Abraham was promised a son by God, despite being more than seventy years old when God first called him out of his homeland (Genesis 12:1–4). Later, God vowed to give Abraham a natural-born child despite his old age, and his elderly wife's lifelong barrenness (Genesis 17:15–16). Both Abraham and Sarah laughed, at first, in response to this prediction (Genesis 17:17; 18:12). Given that Abraham was already well past the average human lifespan (Psalm 90:10), he was "as good as dead," from a worldly perspective.
And yet, just as He said, God delivered on His word. Abraham, a man a full 100 years old, was blessed with a son of his own (Genesis 21:5). Descendants of that son, Isaac, became the nations of Edom and Israel, a massive and uncountable host of people.
